DIMENSIONS
RECOMMENDED SOLDER PAD LAYOUT
Type 252 M series is specially designed to SMD, based on our technology of chip tantalum capacitors acquired
over many years.
This series is high-reliability capacitors developed for devices, such as automotive electric components, to be
used under severe environmental conditions.
１．Face-Down Terminal structure has superior volume efficiency for smaller size and high capacitance.
２．Can be downsized suitable for limited space because face down terminal makes possible for land design.
３．Lead-free and perfect RoHS Compliant
４．AEC-Q200 compliant

Application Notes for Tantalum Solid Electrolytic Capacitor
1. Operating Voltage
Tantalum Solid Electrolytic Capacitor shall be operated at the rated voltage or lower.
Rated voltage: The “rated voltage” refers to the maximum DC voltage that is allowed to be continuously applied between the capacitor
terminals at the rated temperature.
Surge voltage: The “surge voltage” refers to the voltage that is allowed to be instantaneously applied to the capacitor at the rated
temperature or the maximum working temperature. The capacitor shall withstand the voltage when a 30-second cycle of application of
the voltage through a 1000 Ω series resistance is repeated 1000 times in 6-minute periods.
When designing the circuit, the equipment’s required reliability must be considered and appropriate voltage derating must be performed.
2. Application that contain AC Voltage
Special attention to the following 3 items.
(1) The sum of the DC bias voltage and the positive peak value of the AC voltage should not exceed the rated voltage.
(2) Reverse voltage should not exceed the allowable values of the negative peak AC voltage.
(3) Ripple voltage should not exceed the allowable values.
3. Permissible Reverse Voltage
If reverse voltage exceeding the value shown in the following table is applied to the capacitor, there is a fear of a fluctuation of leakage
current and an increase in failure rate. To avoid the permissible reverse voltage, use the capacitor under bias voltage as required.
The above specifications apply for accidental reverse voltage. If reverse voltage is constantly applied to the capacitor, use it with
non-polar connection.
4. Permissible Ripple Voltage
Permissible ripple voltage is determined by the loss of element and heat radiation of case
and lead wire.
This is influenced by capacitance, frequency of ripple, ESR and operating temperature.
The permissible ripple voltage values are shown in our technical document.
5. Application on low-impedance circuit
The failure rate of low impedance circuit at 0.1Ω/V is about five times greater than that of a 1Ω/V circuit. To curtail this higher failure rate,
tantalum capacitors used in low impedance circuits, such as filters for power supplies, particularly switching power supplies, or for noise
by-passing, require that operating voltage be derated to less than half of the rated voltage. Actually, less than 1/3 of the rated voltage is
recommended.
6. Non Polar Application
Tantalum capacitors can be used as a non-polar unit if two capacitors are connected “BACK-TO-BACK” when reserve voltage is applied
at a more than permissible value, or in a purely AC circuit. The two capacitors should both be of the same rated voltage and capacitance
tolerance, and they should both be twice the required capacitance value.
Ripple Voltage: Permissible Ripple Voltage shall not exceed the value allowed for either C1 or C2 (This will be the same, as the
capacitors should be identical.)
Capacitance:（C1×C2）/（C1 + C2）
Leakage Current: If terminal A is (+), the Leakage Current will be equal to C1’s Leakage Current.
If terminal B is (+), the Leakage Current will be equal to C2’s Leakage Current.
7. Soldering
7.1. Preheating
To obtain optimal reliability and solderability conditions, capacitors should be pre-heated at 130 to 200 °C for approximately 60 to 120
seconds.
7.2. Soldering
The body of the capacitor shall not exceed 260 °C during soldering.
(1) Reflow Soldering
Reflow soldering is a process in which the capacitors are mounted on a printed board with solder paste. There are two methods of
Reflow Soldering: Direct and Atmospheric Heat.
· Direct Heat (Hot plate)
During the Direct Heat method, the capacitor has been positioned on a printed board, which is then placed upon a hot plate.
The capacitor maintains a lower temperature than the substrate, which in turn stays at a lower temperature than the hot plate.
· Atmospheric Heat
a) VPS (Vapor Phase Soldering)
During VPS,the substrate is heated by an inert liquid with a high boiling point. The temperature of the capacitor’s body and the
temperature of the substrate are about the same as the atmosphere. This temperature should be below 240°C.
b) Near and Far IR Ray
Due to the heat absorption of the capacitor’s body, the internal temperature of the capacitors may be 20 ~ 30°C higher than the
setting temperature and may exceed 260°C.
Temperature control is crucial in maintaining a temperature of 260 °C or lower.
c) Convention Oven
An infrared ray is the main source of heat in this process. The temperature of the substrate and the capacitors can be maintained
at a similar level by the circulation of heated air, or an inert gas.

(2) Soldering with a Soldering Iron
Soldering with a soldering iron cannot be recommended due to the lack of consistency in maintaining temperatures and process
times. If this method should be necessary, the iron should never touch the capacitor’s terminals, and the temperature of the soldering
iron should never exceed 290°C. The application of the iron should not exceed 3 seconds.
(3) Please consult us for other methods.
8. Solvent cleaning
Cleaning by organic solvent may damage capacitor’s appearance and performance.
However, our capacitors are not effected even when soaked at 20 ~ 30 °C 2-propanol for 5 minutes. When introducing new cleaning
methods or changing the cleaning term, please consult us.
9. Protective Resin Coating
After components are assembled to substrate, a protective resin coating is sometimes applied. As this resin coating cures, it gives
mechanical and thermal stress to Tantalum capacitors. This stress can cause damage to the capacitors, which affects their reliability.
Before using a resin coating, proper research must be done in regards to the material and process to insure that excessive stress will not
be applied to capacitors and other components.
10. Vibration
Approximately 300 G shall be applied to a capacitor, when dropped from 1 meter to a concrete floor.
Although capacitors are made to withstand this drop test, stress from shock due to falling or striking does cause damage to the
capacitors and increases failure rates. Do not subject capacitors to this type of mechanical stress.
11. Ultrasonic cleaning
Matsuo does not recommend Ultrasonic cleaning. This may cause damage to the capacitors, and may even cause broken terminals. If
the Ultrasonic cleaning process will be used, please note the following:
(1)The solvent should not be boiled. (Lower the ultrasonic wave output or use solvent with The high boiling point.)
(2)The recommended wattage is less than 0.5 watts per cm2.
(3)The cleaning time should be kept to a minimum. Also, samples must be swang in the solvlent. Please consult us.
12. Additional Notes
· When more than one capacitor is connected in series, a resistor that can distribute the voltage equally to the capacitors shall be
connected in parallel.
· The capacitor cases shall not be cut even if the mounting space is insufficient.
· During a customers aging process, voltage should remain under the rated voltage at all times.
· Capacitors should never be touched or manipulated while operating.
· Capacitors are not meant to be dismantled.
· When testing capacitors, please examine the power source before conducting test to insure the tester’s polarity and applied voltage.
· In the event of a capacitor burning, smoking, or emitting an offensive smell during operation, please turn the circuit “off” and keep hands
and face away from the burning capacitor.
· If a capacitor be electrical shorted, it becomes hot, and the capacitor element may ignite.
In this case, the printed board may be burnt out.
· Capacitors should be stored at room temperature under low humidity. Capacitors should never be stored under direct sunlight, and
should be stored in an environment containing dust.
· If the capacitors will be operated in a humid environment, they should be sealed with a compound under proper conditions.
· Capacitors should not be stored or operated in environments containing acids, alkalis or active gasses.
· When capacitors are disposed of as “scrap” or waste, they should be treated as Industria Waste since they contain various metals and
polymers.
· Capacitors submitted as samples should not be used for production purposes.
