Explanation
When used at ambient temperature over 70 °C,
0.031 W / element the rated dissipation should be reduced as shown
in Fig.1
Chip jumper : Rated current 1 A (Resistance is less than 50 mΩ)
The rated voltage of each resistor should be calculated from the
equation below, and when the rated voltage exceeds the limiting
element voltage, the limiting element voltage should the maximum
working voltage.
E= P×R
Limiting element voltage : 50 V
E: Rated voltage(V), P: Rated dissipation(W), R: Rated resistance())

! 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 products in this specification are tended for use in general standard applications for general
electric equipment (AV products, household electric appliances, office equipment, information and
communication equipment, etc.); hence, they 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 products; 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 or in outdoor or 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, 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 water or a water-soluble detergent is used in flux cleaning after soldering (pay particular
attention to water-soluble flux.)
(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.
