10. Notice for use
Notice for use
(1)This specification shows the quality and performance of the product in 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 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, etc. in cases where it is forecast
that the failure of this product gives serious damage to human life and others, use fail-safe design
and ensure safety by studying the following items to
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) 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.
3) Where the product is sealed or coated with resin, etc.
4) Where water or a water-soluble detergent is used in cleaning free soldering (Pay particular
attention to soluble flux.)
5) Use in such a place where the product is wetted due to dew condensation.
6) Use in places full of corrosive gases such as sea breeze, Cl
2
, H
2
S, NH
3
, SO
2
, and NO
X
.
7) Use under direct sunlight, in outdoor or in dusty atmospheres.
8) Use in environment with large static electricity or strong electromagnetic waves.
(6)If transient load (heavy load on 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, 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 °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 firm or the body of resistor and may affect resistor’s
performance.
(10)Reflow soldering method shall apply to this product in principle.
