9. 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) Use fail-safe design and ensure safety by carrying out the following items in cases where it
is forecast that the failure of the product gives serious damage to something important like
human life, for instant in traffic transportation equipment (trains, cars, traffic signal
equipment, etc.), medical equipment, aerospace equipment, electric heating appliances,
combustion and gas equipment, rotating equipment, disaster and crime preventive
equipment.
*Ensure safety as the system by setting protective circuits and protective equipment.
*Ensure safety as the system by setting such redundant circuits as do not cause danger by
a single failure.
(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 NOX.
4) Use in environment with large static electricity or strong electromagnetic waves.
5) Where the product is close to a heating component, and 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 water or a water-soluble detergent is used in cleaning free soldering and in flux
cleaning after soldering (Pay particular attention to 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. 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.
(8) When soldering with soldering iron, ground a tip of the 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.
(11) This resistance may change with ESD.
In case of handling this product, please take care as follows.
Environment which static electricity cannot generate easily.
( Recommendation humidity: 40 - 60%)
Wearing of an earth band and a conductive glove.
Connecting surface mounting system to the earth.
Installation of the electric conduction mat on a work table.
10. Storage Method
If the product is stored in the following environments and conditions, the performance and
solderability may be badly affected, avoid the storage in the following environments.
(1) Storage in places full of corrosive gases such as sea breeze, Cl2, H2S, NH3, SO2, and NOX.
(2) Storage in places exposed to direct sunlight.
(3) Storage in places outside the temperature range of 5 deg.C to 35 deg.C and humidity
range of 45 %RH to 85 %RH.
(4) Storage over a year after our delivery (This item also applies to the case where the storage
method specified in item (1) to (3) has been followed.).
