10. Common Precautions in Handling Resistors
! Notice for use
(1) This specification shows the quality and performance of a unit component. Before adoption, be sure to
evaluate and verify the product mounting it in your product.
(2) We take no responsibility for troubles caused by the product usage that is not specified in this specification.
(3) In advance-notification to us is required in case you demand high reliability in the resistors because there is a
possibility that a trouble or a failure in our resistor which is used in your transportation units (e.g. Trains, cars,
ships, traffic signal equipment etc.), ocean floor-equipment, medical equipment, aerospace equipment,
electrothermal goods, combustion and gas equipment, power station control equipment, information control
equipment, rotating equipment, disaster and crime preventive equipment, various safety devices, and the
equivalent equipment may cause critical damage occurrence such as loss of life or property.
In addition, use fail-safe design as mentioned below for preventing extensive damage and for ensuring the
safety:
*Ensure safety by the system in which the protective circuits and/or protective equipment are installed.
*Ensure safety by the system in which a single failure does not cause unsafety by installing such as
redundant circuits.
(4) When a dogma shall be occurred about safety for this product, be sure to inform us rapidly,
operate your technical examination.
(5) The product is designed to use in general standard applications of general electric
equipment (AV products, household electric appliances, office equipment, information and
communication equipment, etc.); hence, it do not take the use under the following special
environments into consideration.
Accordingly, the use in the following special environments, and such environmental conditions may
affect the performance of the product; prior to use, verify the performance, reliability, etc. thoroughly.
1) Use in liquids such as water, oil, chemical, and organic solvent.
2) Use under direct sunlight, in outdoor or in dusty atmospheres.
3) Use in places full of corrosive gases such as sea breeze, Cl₂, H₂S, NH₃, SO₂, and NO_X.
4) Use in environment with large static electricity or strong electromagnetic waves or
strong radial ray.
5) Where the product is close to a heating component, or where an inflammable such as
a polyvinyl chloride wire is arranged close to the product.
6) Where the resistor is sealed or coated with resin etc.
7) Where solvent, water, or water-soluble detergent is used in cleaning free soldering and in flux cleaning
after soldering. (Pay particular attention to water-soluble flux.)
8) Use in such a place where the product is wetted due to dew condensation.
(6) If transient load (heavy load in a short time) like pulse is expected to be applied, carry out
evaluation and confirmation test with resistors actually mounted on your own board.
When the load of more than rated power is applied under the load condition at steady state, it
may impair performance and/or reliability of resistor. Never exceed the rated power and
rated voltage. Temperature of resistors may become high even with specified conditions. Please confirm
safety of heat from resistors on print circuit board and components around them. When the product shall be
used under special condition, be sure to ask us in advance.
(7) Halogen type (Chlorine type, Bromine type, etc.) or other high-activity flux is not
recommended as the residue may affect performance or reliability of resistors.
Strong acid flux, water soluble-flux and flux including fluorine ion shall not be used.
(8) When soldering with soldering iron, never touch the body of the chip resistor with a tip of
the soldering iron. When using a soldering iron with a tip at high temperature, solder for a
time as short as possible. (three seconds or less up to 350 deg.C)
(9) Avoid physical shock to the resistor and nipping of the resistor with hard tool (a pair of
pliers or tweezers) as it may damage protective film or the body of resistor and may affect
resistor’s performance.
(10) Avoid immersion of chip resistor in solvent for long time. Use solvent after the effect of
immersion is confirmed.
