2. Product Characteristic data

2-1. Capacitance

The capacitance is the ratio of the change in an electric charge according to voltage change.

Due to the fact that the capacitance may be subject to change with the measured voltage and

frequency, it is highly recommended to measure the capacitance based on the following

conditions.

2-1-1. Measure capacitance with voltage and frequency specified in this document.

Regarding the voltage/frequency condition for capacitance measurement of each MLCC model,

please make sure to follow a section “C. Reliability test Condition - Capacitance” in this document.

The following table shows the voltage and frequency condition according to the capacitance

range.

[The voltage and frequency condition according to MLCC the capacitance range]

◆ Class I

Capacitance Frequency Voltage

≤ 1,000 pF 1 MHz ± 10%

0.5 ~ 5 Vrms

> 1,000 pF 1 kHz ± 10%

◆ Class II

Capacitance Frequency Voltage

≤ 10 ㎌ 1 kHz ± 10% 1.0 ± 0.2 Vrms

> 10 ㎌ 120 Hz ± 20% 0.5 ± 0.1 Vrms

Exception* 1 kHz ± 10% 0.5 ± 0.1 Vrms

Capacitance shall be measured after the heat treatment of 150+0/-10℃

for 1hr, leaving at room temperature for 24±2hr. (Class II)

2-1-2. It is recommended to use measurement equipment with the ALC (Auto Level Control) option.

The reason is that when capacitance or measurement frequency is high, the output voltage of

measurement equipment can be lower than the setting voltage due to the equipment limitation.

Note that when capacitance or measurement frequency is excessively high, the measurement

equipment may show ALC off warning and provide a lower output voltage than the setting

voltage even with ALC option selected. It is necessary to ensure the output voltage of

measurement equipment is the same as the setting voltage before measuring capacitance.

MLCC Product Manual

2-1-3. Capacitance value of high dielectric constant (Class II) MLCC changes with applied AC and DC

voltage. Therefore, it is necessary to take into account MLCC’s AC voltage characteristics and DC-

bias voltage characteristics when applying MLCC to the actual circuit.

2-1-4. The capacitance is in compliance with the EIA RS-198-1-F-2002.

2-2. Tan δ (DF)

2-2-1. An ideal MLCC’s energy loss is zero, but real MLCC has dielectric loss and resistance loss of

electrode. DF (Dissipation Factor) is defined as the ratio of loss energy to stored energy and

typically being calculated as percentage.

2-2-2. Quality factor (Q factor) is defined as the ratio of stored energy to loss energy.

The equation can be described as 1/DF. Normally the loss characteristic of Class I MLCC is

presented in Q, since the DF value is so small whereas the loss characteristic of Class II MLCC is

presented in DF.

2-2-3. It is recommended to use Class I MLCC for applications to require good linearity and low loss

such as coupling circuit, filter circuit and time constant circuit.

2-3. Insulation Resistance

Ceramic dielectric has a low leakage current with DC voltage due to the high insulating properties.

Insulation resistance is defined as the ratio of a leakage current to DC voltage.

2-3-1. When applying DC voltage to MLCC, a charging current and a leakage current flow together at

the initial stage of measurement. While the charging current decreases, and insulation resistance

(IR) in MLCC is saturated by time. Therefore, insulation resistance shall be measured 1 minute after

applying the rated voltage.

2-4. Capacitance Aging

The aging characteristic is that the high dielectric (Class II) MLCC decreases capacitance

value over time. It is also necessary to consider the aging characteristic with voltage and

temperature characteristics when Class II MLCC is used in circuitry.

MLCC Product Manual

2-4-1. In general, aging causes capacitance to decrease linearly with the log of time as shown in the

following graph. Please check with SEMCO for more details, since the value may vary between

different models.

2-4-2. After heat treatment (150 °C, 1hour), the capacitance decreased by aging is recovered, so aging

should be considered again from the time of heat treatment.

[ Example of Capacitance Aging ]

* Sample : C0G, X7R, X5R

2-5. Temperature Characteristics of Capacitance (TCC)

Please consider temperature characteristics of capacitance since the electrical characteristics such as

capacitance changes which is caused by a change in ceramic dielectric constant by temperature.

2-5-1. It is necessary to check the values specified in section “C. Reliability test Condition–Temperature

Characteristics” for the temperature and capacitance change range of MLCC.

[ Example of Temperature Characteristics (X5R) ] [ Example of Bias TCC ]

* Sample : 10uF, Rated voltage 6.3V * Sample : 10uF, Rated voltage 6.3V

MLCC Product Manual

2-5-2. When selecting MLCC, it is necessary to consider the heat characteristics of a system, room

temperature and TCC of MLCC, since the applied temperature may change the capacitance of

MLCC.

2-5-3. In addition, Bias TCC of MLCC should be taken into account when DC voltage is applied to MLCC.

2-6. Self-heating Temperature

It is necessary to design the system, with considering self-heating generated by the ESR

(Equivalent Series Resistance) of MLCC when AC voltage or pulse voltage is applied to MLCC.

2-6-1. When MLCC is used in an AC voltage or pulse voltage circuit, self-heating is generated when AC

or pulse current flows through MLCC. Short-circuit may be occurred by the degradation of MLCC’s

insulating properties.

2-6-2. The reliability of MLCC may be affected by MLCC being used in an AC voltage or pulse voltage

circuit, even the AC voltage or the pulse voltage is within the range of rated voltage.

Therefore, make sure to check the following conditions.

1) The surface temperature of MLCC must stay within the maximum operating temperature after

AC or Pulse voltage is applied.

2) The rise in increase by self-heating of MLCC must not exceed 20℃

[ Example of Ripple current ]

* Sample : X5R 10uF, Rated voltage 6.3V

MLCC Product Manual

2-7. DC & AC Voltage Characteristics

It is required to consider voltage characteristics in the circuit since the capacitance value of high

dielectric constant MLCC(Class II) is changed by applied DC & AC voltage.

2-7-1. Please ensure the capacitance change is within the allowed operating range of a system. In

particular, when high dielectric constant type MLCC (Class II) is used in circuit with narrow allowed

capacitance tolerance, a system should be designed with considering DC voltage, temperature

characteristics and aging characteristics of MLCC.

[ Example of DC Bias characteristics ]

* Sample : X5R 10uF, Rated voltage 6.3V

2-7-2. It is necessary to consider the AC voltage characteristics of MLCC and the AC voltage of a system,

since the capacitance value of high dielectric constant type MLCC (Class II) varies with the applied

AC voltage.

[ Example of AC voltage characteristics ]

* Sample : X5R 10uF, Rated voltage 6.3V

MLCC Product Manual

2-8. Impedance Characteristic

Electrical impedance (Z) of MLCC is the measurement of the opposition that MLCC presents to a

current (I) when a voltage (V) is applied. It is defined as the ratio of the voltage to the current

(Z=V/I). Impedance extends the concept of resistance to AC circuits and is a complex number

consisting of the real part of resistance (R) and the imaginary part of reactance (X) as Z=R+jX.

Therefore, it is required to design circuit with consideration of the impedance characteristics of

MLCC based on the frequency ( Z = R + jX )

2-8-1. MLCC operates as a capacitor in the low frequency and its reactance (XC) decreases as frequency

increases ( X_C=1/j2πfC ) where f is frequency and C is capacitance.

The resistance (ESR; Equivalent Series Resistance) of MLCC in the low frequency mainly comes

from the loss of its dielectric material.

2-8-2. MLCC operates as an inductor in the high frequency and the inductance of MLCC is called ESL

(Equivalent Series Inductance). The reactance (XL) of MLCC in the high frequency increases as

frequency increases ( X_L=j2πf∙ESL ). The resistance (ESR) of MLCC in the high frequency mainly

comes from the loss of its electrode metal.

2-8-3. SRF (Self Resonant Frequency) of MLCC is the frequency where its capacitive reactance (XC) and

inductive reactance(XL) cancel each other and the impedance of MLCC has only ESR at SRF.

2-8-4. The impedance of MLCC can be measured by a network analyzer or an impedance analyzer.

When using the network analyzer, please note that the small-signal input may lead to the

impedance of low capacitance caused by the AC voltage characteristic of MLCC.

MLCC Product Manual

3. Electrical & Mechanical Caution

3-1. Derating

MLCC with the test voltage at 100% of the rated voltage in the high temperature resistance test

are labeled as “derated MLCC.” For this type of MLCC, the voltage and temperature should be

derated as shown in the following graph for the equivalent life time of a normal MLCC with the

test voltage at 150% of the rated voltage in the high temperature resistance test.

3-1-1. The derated MLCC should be applied with the derating voltage and temperature as shown in the

following graph.

3-1-2. The “Temperature of MLCC” in the x-axis of the graph below indicates the surface temperature of

MLCC including self-heating effect. The “Voltage Derating Ratio” in the y-axis of the graph below

gives the maximum operating voltage of MLCC with reference to the maximum voltage (Vmax) as

3-2. Applied Voltage

The actual applied voltage on MLCC should not exceed the rated voltage set in the specifications.

3-2-1. Cautions by types of voltage applied to MLCC

· For DC voltage or DC+AC voltage, DC voltage or the maximum value of DC + AC voltage should

not exceed the rated voltage of MLCC.

· For AC voltage or pulse voltage, the peak-to-peak value of AC voltage or pulse voltage

should not exceed the rated voltage of MLCC.

· Abnormal voltage such as surge voltage, static electricity should not exceed the rated voltage of

MLCC.

[Types of Voltage Applied to the Capacitor]

DC Voltage AC Voltage DC+AC Voltage 1 DC+AC Voltage 2 DC+Pulse Voltage

3-2-2. Effect of EOS (Electrical Overstress)

· Electrical Overstress such as a surge voltage or EOS can cause damages to MLCC, resulting in

the electrical short failure caused by the dielectric breakdown in MLCC.

· Down time of MLCC is varied with the applied voltage and the room temperature and a

dielectric shock caused by EOS can accelerate heating on the dielectric. Therefore, it can bring

about a failure of MLCC in a market at the early stage.

· Please use caution not to apply excessive electrical overstress including spike voltage MLCC when

preparing MLCC for testing or evaluating.

(1) Surge

When the overcurrent caused by surge is applied to MLCC, the influx of current into MLCC can

induce the overshooting phenomenon of voltage as shown in the graph below and result in the

electrical short failure in MLCC. Therefore, it is necessary to be careful to prevent the influx of

surge current into MLCC.

(2) ESD (Electrostatic Discharge)

Since the voltage of the static electricity is very high but the quantity of electric charge is small

compared to the surge, ESD can cause damage to MLCC with low capacitance as shown in the

MLCC Product Manual

following graph, whereas surge with lots of electric charge quantity can cause damages to even

high capacitance MLCC.

[ Example of Surge applied to MLCC ] [ Example of ESD applied to MLCC ]

* Simulation for ESD 8kV

3-3. Vibration

Please check the types of vibration and shock, and the status of resonance.

Manage MLCC not to generate resonance and avoid any kind of impact to terminals.

When MLCC is used in a vibration environment, please make sure to contact us for the situation

and consider special MLCC such as Soft-term, etc.

3-4. Shock

Mechanical stress caused by a drop may cause damages to a dielectric or a crack in MLCC

Do not use a dropped MLCC to avoid any quality and reliability deterioration.

When piling up or handling printed circuit boards, do not hit MLCC with the corners of a PCB to

prevent cracks or any other damages to the MLCC.

3-5. Piezo-electric Phenomenon

MLCC may generate a noise due to vibration at specific frequency when using the high dielectric

constant MLCC (Class Ⅱ) at AC or Pulse circuits.

MLCC may cause a noise if MLCC is affected by any mechanical vibrations or shocks.

MLCC Product Manual

4. Process of Mounting and Soldering

4-1. Mounting

4-1-1. Mounting position

It is recommended to locate the major axis of MLCC in parallel to the direction in which the stress

is applied.

Not recommended Recommended

4-1-2. Cautions during mounting near the cutout

Please take the following measures to effectively reduce the stress generated from the cutting of

PCB. Select the mounting location shown below, since the mechanical stress is affected by a

location and a direction of MLCC mounted near the cutting line.

4-1-3. Cautions during mounting near screw

If MLCC is mounted near a screw hole, the board deflection may be occurred by screw torque.

Mount MLCC as far from the screw holes as possible.

Not recommended Recommended

MLCC Product Manual

4-2. Caution before Mounting

4-2-1. It is recommended to store and use MLCC in a reel. Do not re-use MLCC that was isolated from

the reel.

4-2-2. Check the capacitance characteristics under actual applied voltage.

4-2-3. Check the mechanical stress when actual process and equipment is in use.

4-2-4. Check the rated capacitance, rated voltage and other electrical characteristics before assembly.

Heat treatment must be done prior to measurement of capacitance.

4-2-5. Check the solderability of MLCC that has passed shelf life before use.

4-2-6. The use of Sn-Zn based solder may deteriorate the reliability of MLCC.

4-3. Cautions during Mounting with Mounting (pick-and-place) Machines

4-3-1. Mounting Head Pressure

Excessive pressure may cause cracks in MLCC.

It is recommended to adjust the nozzle pressure within the maximum value of 300g.f.

Additional conditions must be set for both thin film and special purpose MLCC.

4-3-2. Bending Stress

When using a two-sided substrate, it is required to mount MLCC on one side first before

mounting on the other side due to the bending of the substrate caused by the mounting head.

Support the substrate as shown in the picture below when MLCC is mounted on the other side.

If the substrate is not supported, bending of the substrate may cause cracks in MLCC.

4-3-3. Suction nozzle

Dust accumulated in a suction nozzle and suction mechanism can impede a smooth movement of

the nozzle. This may cause cracks in MLCC due to the excessive force during mounting.

If the mounting claw is worn out, it may cause cracks in MLCC due to the uneven force during

positioning.

A regular inspection such as maintenance, monitor and replacement for the suction nozzle and

mounting claw should be conducted.

MLCC Product Manual

4-4. Reflow soldering

MLCC is in a direct contact with the dissolved solder during soldering, which may be exposed to

potential mechanical stress caused by the sudden temperature change.

Therefore, MLCC may be contaminated by the location movement and flux.

For the reason, the mounting process must be closely monitored.

4-4-1. Reflow Profile

[Reflow Soldering Conditions]

Use caution not to exceed the peak temperature (260℃) and time (30sec) as shown.

Pre-heating is necessary for all constituents including the PCB to prevent the mechanical damages

on MLCC. The temperature difference between the PCB and the component surface must be kept

to the minimum.

As for reflow soldering, it is recommended to keep the number of reflow soldering to less than

three times. Please check with us when the number of reflow soldering needs to exceed three

times. Care must be exercised especially for the ultra-small size, thin film and high capacitance

MLCC as they can be affected by thermal stress more easily.

MLCC Product Manual

4-4-2. Reflow temperature

The following quality problem may occur when MLCC is mounted with a lower temperature than

the reflow temperature recommended by a solder manufacturer. The specified peak temperature

must be maintained after taking into consideration the factors such as the placement of

peripheral constituent and the reflow temperature.

･Drop in solder wettability

･Solder voids

･Potential occurrence of whisker

･Drop in adhesive strength

･Drop in self-alignment properties

･Potential occurrence of tombstones

4-4-3. Cooling

Natural cooling with air is recommended.

4-4-4. Optimum solder flux for reflow soldering

· Overly the thick application of solder pastes results in an excessive solder fillet height.

This makes MLCC more vulnerable to the mechanical and thermal stress from the board, which

may cause cracks in MLCC.

· Too little solder paste results in a lack of the adhesive strength, which may cause MLCC to

isolate from PCB

· Check if solder has been applied uniformly after soldering is completed.

· It is required to design a PCB with consideration of a solder land pattern and its size to apply an

appropriate amount of solder to MLCC. The amount of the solder at the edge may impact

directly on cracks in MLCC.

· The design of a suitable solder land is necessary since the more the solder amount is,

the larger the force MLCC experiences and the higher the chance MLCC cracks.

Too Much Solder

large stress may cause cracks

Not enough solder

Weak holding force may cause bad

connections or detaching of the capacitor

MLCC Product Manual

4-5. Flow soldering

4-5-1. Flow profile

[Flow Soldering Conditions]

Take caution not to exceed peak temperature (260℃) and time (5sec) as shown.

In case of flow soldering, only 1608(0603inch), 2012(0805inch), 3216(1206inch) case size are

recommended to use.

Please contact us before use the type of high capacitance and thin film MLCC for some

exceptions that may be caused.

4-5-2. Caution before Flow soldering

· When a sudden heat is applied to MLCC, the mechanical rigidity of MLCC is deteriorated by the

internal deformation of MLCC. Preheating all the constituents including PCB is required to prevent

the mechanical damages on MLCC. The temperature difference between the solder and the

surface of MLCC must be kept to the minimum.

· If the flow time is too long or the flow temperature is too high, the adhesive strength with PCB

may be deteriorated by the leaching phenomenon of the outer termination, or the capacitance

value may be dropped by weak adhesion between the internal termination and the outer

termination.

MLCC Product Manual

4-6. Soldering Iron

Manual soldering can pose a great risk on creating thermal cracks in MLCC. The high temperature

soldering iron tip may come into a direct contact with the ceramic body of MLCC due to the

carelessness of an operator. Therefore, the soldering iron must be handled carefully, and close

attention must be paid to the selection of the soldering iron tip and to temperature control of the

tip.

4-6-1. How to use a soldering Iron

· In order to minimize damages on MLCC, preheating MLCC and PCB is necessary.

A hot plate and a hot air type preheater should be used for preheating

. Do not cool down MLCC and PCB rapidly after soldering.

· Keep the contact time between the outer termination of MLCC and the soldering iron as short as

possible. Long soldering time may cause problems such as adhesion deterioration by the

leaching phenomenon of the outer termination.

4-6-2. How to use a spot heater

· Compared to local heating using a solder iron, heat by a spot heater heats the overall MLCC and

the PCB, which is likely to lessen the thermal shocks.

For a high density PCB, a spot heater can prevent the problem to connect between a solder iron

and MLCC directly.

· If the distance from the air nozzle outlet to MLCC is too close, MLCC may be cracked due to the

thermal stress. Follow the conditions set in the table below to prevent this problem.

The spot heater application angle as shown in the figure is recommended to create a suitable

solder fillet shape.

· In case that heat of higher than 350℃ is applied to MLCC containing epoxy material,

the epoxy material in MLCC may be damaged by heat.

MLCC Product Manual

4-6-3. Cautions for re-work

· Too much solder amount will increase the risk of PCB bending or cause other damages.

· Too little solder amount will result in MLCC breaking loose from the PCB due to the

inadequate adhesive strength.

· Check if the solder has been applied properly and ensure the solder fillet has a proper shape.

* Soldering wire below ø0.5mm is required for soldering.

4-7. Cleaning

4-7-1. In general, cleaning is unnecessary if rosin flux is used.

When acidic flux is used strongly, chlorine in the flux may dissolve into some types of cleaning

fluids, thereby affecting the performance of MLCC.

This means that the cleansing solution must be carefully selected and should always be new.

4-7-2. Cautions for cleaning

MLCC or solder joint may be cracked with the vibration of PCB, if ultrasonic vibration is too strong

during cleaning. When high pressure cleaning equipment is used, test should be done for the

cleaning equipment and its process before the cleaning in order to avoid damages on MLCC.

4-8. Cautions for using electrical measuring probes

· Confirm the position of the support pin or jig when checking the electrical performance of MLCC

after mounting on the PCB.

· Watch for PCB bending caused by the pressure of a test-probe or other equipment.

· If the PCB is bent by the force from the test probe, MLCC may be cracked or the solder joint may

be damaged.

· Avoid PCB flexing by using the support pin on the back side of the PCB.

· Place equipment with the support pin as close to the test-probe as possible.

· Prevent shock vibrations of the board when the test-probe contacts a PCB.

Not recommended Recommended

4-9. Printed Circuit Board Cropping

· Do not apply any stress to MLCC such as bending or twisting the board after mounting MLCC

on the PCB.

· The stress as shown may cause cracks in MLCC when cutting the board.

· Cracked MLCC may cause degradation to the insulation resistance, thereby causing short circuit.

· Avoid these types of stresses applied to MLCC.

[Bending] [Twisting]

4-9-1. Cautions for cutting PCB

Check a cutting method of PCB in advance.

The high density board is separated into many individual boards after the completion of soldering.

If the board is bent or deformed during separation, MLCC may be cracked.

Carefully select a separation method that minimizes the deformation of the PCB.

MLCC Product Manual

4-10. Assembly Handling

4-10-1. Cautions for PCB handling

Hold the edges of the board mounted with MLCC with both hands since holding with one hand

may bend the board.

Do not use dropped boards, which may degrade the quality of MLCC.

4-10-2. Mounting other components

Pay attention to the following conditions when mounting other components on the back side of

The board after MLCC has been mounted on the front side.

When the suction nozzle is placed too close to the board, board deflection stress may be

applied to MLCC on the back side, resulting in cracks in MLCC.

Check if proper value is set on each chip mounter for a suction location, a mounting gap and a

suction gap by the thickness of components.

4-10-3. Board mounting components with leads

If the board is bent when inserting components (transformer, IC, etc.) into it, MLCC or solder

joint may be cracked.

Pay attention to the following:

· Reduce the stress on the board during insertion by increasing the size of the lead insertion

hole.

· Insert components with leads into the board after fixing the board with support pins or a

dedicated jig.

· Support the bottom side of the board to avoid bending the board.

· Check the status of the height of each support pin regularly when the support pins are used.

Not recommended Recommended

MLCC Product Manual

4-10-4. Socket and / or connector attach / detach

Since the insertion or removal from sockets and connectors may cause the board to bent, make

sure that MLCC mounted on the board should not be damaged in this process.

4-10-5. Fastening screw

When attaching a shield on a board, the board may be bent during a screw tightening work

Pay attention to the following conditions before performing the work.

· Plan the work to prevent the board from bending

· Use a torque driver to prevent over-tightening of the screw.

· Since the board may be bent by soldering, use caution in tightening the screw.

4-11. Adhesive selection

Pay attention to the following if an adhesive is used to position MLCC on the board before

soldering.

4-11-1. Requirements for Adhesives

· They must have enough adhesive strength to prevent MLCC from slipping or moving during

the handling the board.

· They must maintain their adhesive strength when exposed to soldering temperatures.

· They should not spread when applied to the PCB.

· They should have a long pot life.

· They should hardened quickly.

· They should not corrode the board or MLCC materials.

· They should be an insulator type that does not affect the characteristic of MLCC.

· They should be non-toxic, not harmful, and particularly safe when workers touch theadhesives.

4-11-2. Caution before Applying Adhesive

Check the correct application conditions before attaching MLCC to the board with an adhesive.

If the dimension of land, the type of adhesives, the amount of coating, the contact surface areas,

the curing temperature, or other conditions are not appropriate, it may degrade the MLCC

performance.

MLCC Product Manual

4-11-3. Cautions for selecting Adhesive

Depending on the type of the chosen adhesive, MLCC insulation resistance may be degraded.

In addition, MLCC may be cracked by the difference in contractile stress caused by the different

contraction rate between MLCC and the adhesive.

4-11-4. Cautions for the amount of applied adhesive and curing temperature

· The inappropriate amount of the adhesive cause the weak adhesive strength, resulting in the a

mounting defect in MLCC

· Excessive use of the adhesive may cause a soldering defect, loss of electrical connection,

incorrect curing, or slippage of a mounting position, thereby an inflow of the adhesive onto a

land section should be avoided.

· If the curing temperature is too high or the curing time is too long, the adhesive strength will

be degraded. In addition, oxidation both on the outer termination (Sn) of MLCC and the

surface of the board may deteriorate the solderability.

4-12. Flux

4-12-1. The excessive amount of flux generates excessive flux gases which may deteriorate solderability.

Therefore, apply the flux thin and evenly as a whole.

4-12-2. Flux with a high ratio of halogen may oxidize the outer termination of MLCC, if cleaning is not

done properly. Therefore, use flux with a halogen content of 0.1% max.

4-12-3. Strong acidic flux can degrade the MLCC performance

4-12-4. Check the solder quality of MLCC and the amount of remaining flux surrounding MLCC after the

mounting process.

4-13. Coating

4-13-1. Crack caused by Coating

A crack may be caused in the MLCC due to amount of the resin and stress of thermal

contraction of the resin during coating process.

During the coating process, the amount of resin and the stress of thermal contraction of the

resin may cause cracks in MLCC

The difference of thermal expansion coefficient between the coating, or a molding resin may

cause destruction, deterioration of insulation resistance or dielectric breakdown of MLCC such

as cracks or detachment, etc.

MLCC Product Manual

4-13-2. Recommended Coating material

· A thermal expansion coefficient should be as close to that of MLCC as possible.

· A silicone resin can be used as an under-coating to buffer the stress.

· The resin should have a minimum curing contraction rate.

· The resin should have a minimum sensitivity (ex. Epoxy resin).

· The insulation resistance of MLCC can be deteriorated if a high hygroscopic property resin is

used in a high humidity condition.

· Do not use strong acid substances due to the fact that coating materials inducing a family of

halogen substances and organic acid may corrode MLCC.

MLCC Product Manual

5. Design

5-1. Circuit design

When the board is dropped or bent, MLCC mounted on the board may be short-circuited by the

drop in insulation resistance. Therefore, it is required to install safety equipment such as a fuse to

prevent additional accidents when MLCC is short-circuited, otherwise, electric short and fire may

occur. This product is not a safety guaranteed product..

5-2. PCB Design

5-2-1. Unlike lead type components, SMD type components that are designed to be mounted directly

on the board are fragile to the stress. In addition, they are more sensitive to mechanical and

thermal stress than lead type components.

5-2-2. MLCC crack by PCB material type

A great difference of the thermal expansion coefficient between PCB and MLCC causes thermal

expansion and contraction, resulting in cracks in MLCC. Even though MLCC is mounted on a

board with a fluorine resin or on a single-layered glass epoxy, cracks in MLCC may occur.

5-3. Design system evaluation

5-3-1. Evaluate the actual design with MLCC to make sure there is no functional issue or violation of

specifications of the finished goods.

5-3-2. Please note that the capacitance may differ based on the operating condition of the actual system

since Class 2 MLCC capacitance varies with applied voltage and temperature.

5-3-3. Surge resistance must be evaluated since the excessive surge caused by the inductance of the

actual system may apply to MLCC.

5-3-4. Note the actual MLCC size and the termination shape.

MLCC Product Manual

5-4 Land dimension

The recommended land dimension is determined by evaluating the actual SET and a board.
