Safety Precautions (Common precautions for Fixed Resistors)
• When using our products, no matter what sort of equipment they might be used for, be sure to make a written
agreement on the specifications with us in advance. The design and specifications in this catalog are subject
to change without prior notice.
• Do not use the products beyond the specifications described in this catalog.
• This catalog explains the quality and performance of the products as individual components. Before use, check
and evaluate their operations when installed in your products.
• Install the following systems for a failsafe design to ensure safety if these products are to be used in equip ment
where a defect in these products may cause the loss of human life or other significant dam age, such as damage to
vehicles (automobile, train, vessel), traffic lights, medical equipment, aerospace equipment, electric heating
appliances, combustion/gas equipment, rotating equipment, and disaster/crime prevention equipment.
✽ Systems equipped with a protection circuit and a protection device
✽ Systems equipped with a redundant circuit or other system to prevent an unsafe status in the event of a sin gle fault
(1) Precautions for use
• These products are designed and manufactured for general and standard use in general elec tron ic equipment
(e.g. AV equipment, home electric appliances, office equipment, information and communication equipment)
• These products are not intended for use in the following special conditions. Before using the products,
carefully check the effects on their quality and performance, and determine whether or not they can be used.
1. In liquid, such as water, oil, chemicals, or organic solvent
2. In direct sunlight, outdoors, or in dust
3. In salty air or air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2
4. Electric Static Discharge (ESD) Environment
These components are sensitive to static electricity and can be damaged under static shock (ESD).
Please take measures to avoid any of these environments.
Smaller components are more sensitive to ESD environment.
5. Electromagnetic Environment
Avoid any environment where strong electromagnetic waves exist.
6. In an environment where these products cause dew condensation
7. Sealing or coating of these products or a printed circuit board on which these products are mounted, with
resin or other materials
• These products generate Joule heat when energized. Carefully position these products so that their heat will
not affect the other components.
• Carefully position these products so that their temperatures will not exceed the category temperature range due
to the effects of neighboring heat-generating components. Do not mount or place heat-generating components
or inflammables, such as vinyl-coated wires, near these products.
• Note that non-cleaning solder, halogen-based highly active flux, or water-soluble flux may deteriorate the
performance or reliability of the products.
• Carefully select a flux cleaning agent for use after soldering. An unsuitable agent may deteriorate the performance
or reliability. In particular, when using water or a water-soluble cleaning agent, be careful not to leave water
residues. Otherwise, the insulation performance may be deteriorated.
(2) Precautions for storage
The performance of these products, including the solderability, is guaranteed for a year from the date of ar riv al
at your company, provided that they remain packed as they were when delivered and stored at a tem per a ture
of 5 °C to 35 °C and a relative humidity of 45 % to 85 %.
Even within the above guarantee periods, do not store these products in the following conditions. Otherwise,
their electrical performance and/or solderability may be deteriorated, and the packaging materials (e.g. taping
materials) may be deformed or deteriorated, resulting in mounting failures.
1. In salty air or in air with a high concentration of corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2
2. In direct sunlight
<Package markings>
Package markings include the product number, quantity, and country of origin.
In principle, the country of origin should be indicated in English.
This is all for the common precautions. Also refer to the "CAUTION AND WARNING" section located on the back of the
front cover of this catalog and precautions for individual products shown in the sub se quent pages.

The following are precautions for individual products. Please also refer to the common precautions for Fixed Resistors
in this catalog.
1. Take measures against mechanical stress during and after mounting of Surface Mount Resistors (hereafter called the
resistors) so as not to damage their electrodes and protective coatings.
Be careful not to misplace the resistors on the land patterns. Otherwise, solder bridging may occur.
2. Keep the rated power and ambient temperature within the specified derating curve.
Some circuit boards, wiring patterns, temperatures of heat generated by adjacent components, or am bi ent
tem per a tures can become factors in the rise of the temperature of the re sis tors, regardless of the level of power
applied. Therefore, check the conditions before use and op ti mize them so as not to damage the boards and peripheral
components.
Make sure to contact us before using the resistors under special conditions.
3. If a transient load (heavy load in a short time) like a pulse is expected to be applied, check and evaluate the
operations of the resistors when installed in your products before use.
Never exceed the rated power. Otherwise, the performance and/or reliability of the resistors may be impaired.
4. Before using halogen-based or other high-activity flux, check the possible effects of the flux residues on the
per for mance and reliability of the resistors.
5. When soldering with a soldering iron, never touch the resistors'bodies with the tip of the soldering iron. When using a
soldering iron with a high temperature tip, finish soldering as quickly as possible (within three seconds at 350 °C max.).
6. As the amount of applied solder becomes larger, the mechanical stress applied to the resistors increases, causing
problems such as cracks and faulty characteristics. Avoid applying an excessive amounts of solder.
7. When the resistors' protective coatings are chipped, flawed, or removed, the characteristics of the resistors may be
impaired. Take special care not to apply mechanical shock during automatic mounting or cause damage during
handling of the boards with the resistors mounted.
8. Do not apply shock to the resistors or pinch them with a hard tool (e.g. pliers and tweezers). Otherwise, the resistors'
protective coatings and bodies may be chipped, affecting their performance.
9. Avoid excessive bending of printed circuit boards in order to protect the resistors from abnormal stress.
10. Do not immerse the resistors in solvent for a long time. Before using solvent, carefully check the effects of im mer sion.
11. Transient voltage
If there is a possibility that the transient phe nom e non (significantly high voltage ap plied in a short time) may
oc cur or that a high voltage pulse may be applied, make sure to evaluate and check the char ac ter is tics of
Fixed Metal (Oxide) Film Resistors mounted on your product rather than only depending on the calculated
pow er limit or steady-state conditions to complete the de sign or decide to use the resistors.
12. Do not apply excessive tension to the terminals.

to resistor element. Do not place vinyl wires around resistors and be sure to consider where the resistors will be
placed.
Safety Precautions
The following are precautions for individual products. Please also refer to the common precautions for Fixed Resistors in
this catalog.
1. Transient voltage
If there is a possibility that the transient phenomenon (significantly high voltage applied in a short time) may
occur or that a high voltage pulse may be applied, make sure to evaluate and check the characteristics of
Metal(Oxide) Film Resistors (hereafter called the resistors) mounted on your product rath er than only depending
on the calculated pow er limit or steady-state conditions to complete the design or decide to use the resistors.
2. The resistors are covered with a special coating. Do not apply shock or vibration to them, or pinch them with
long-nose pliers. Otherwise, the resistors may be damaged.
3. Do not apply excessive tension to the lead-connect ed sections. When bending the lead wire, do not apply
excessive stress to the resistors and provide the wire with a natural curvature.
4. Do not brush the resistors during or after the cleaning process, which may be conducted after soldering.
Otherwise, the coating film may be damaged.

The following are precautions for individual products. Please also refer to the common precautions for Fixed Resistors
in this catalog.
1. Checking the fusing conditions
1) Fusing characteristics differ depending on the type, shape, and resistance. Check the fusing conditions be fore
selecting the type of Metal Film Fusing Re sis tors (hereafter called the fusing resistor) to be used.
2) Use the fusing resistors under the maximum open circuit voltage. Otherwise, arc ing may oc cur when a volt age
much higher than the rated one is applied in the event of an abnormality in the circuit, or when a high volt age
is applied after fus ing.
3) Under abnormal conditions of a constant voltage circuit, a current of about 2 or 3 times the initial abnormal
current passes through, accelerating the speed at which the fusing resistors blows. When using a constant
current circuit, carefully check the conditions because the fusing resistors may not blow in a constant cur rent
circuit.
2. Checking for pulse voltage, impact voltage, and transient voltage
Make sure to evaluate and check the fusing resistors mounted on your product if they are to be mounted on a
circuit that generates an impact voltage, or if there is a possibility that the tran sient phenomenon (sig nifi cant ly
high voltage applied in a short time) may oc cur or that a pulse voltage with a high peak volt age may be ap plied.
Make sure to consult our sales staff before using the fusing resistors under spe cial con di tions.
3. Conditions of use in a steady state
Make sure that the load conditions have a suffi cient allowance for the power de r at ing curve. The char ac ter is tics of
the fusing resistors are set by using a constant voltage circuit.
4. The solvent resistance of the fusing resistors is not assured. If you use a solvent for clean ing after soldering or
other processes, make sure to consult our sales staff before use and per form a prior test and evaluation to
ensure that the solvent will not affect the re li abil i ty of the fusing resistors.
