General Specifications
Notes for leaded resistors
1) Storage
Recommended storage condition is room temperature 0 -30
and humidity 65% or less.
Please avoid using or storing in the environment of high temperature, high humidity, high dust,
high density of harmful gas such as chlorine system, sulfuric acid system gas and so on,
Please also avoid long-term storage and use it within one year after delivery.
2) Load condition
Even if used within load-derating curve, please consider self-heating of the resistor, ambient
temperature and heat influence from other parts. In order to use in stable condition for long period
of time, please take load-derating sufficiently.
3) Mounting position
When placing other electronic parts around this resistor, please position the other parts at least
5mm or more apart from this resistor.
4) Soldering
When soldering, please minimize heat influence of the soldering.
Please finish soldering within 7 seconds at temperature 260 or less. In case of manual work by
soldering iron, please finish within 3 seconds at iron tip temperature of 380 or less.
5) Shock against resistor
Please keep in mind that there is fear of breakage if strong shock applied against this resistor.
Especially when automatic insertion machine used, breakage by the shock at the time of mounting
may be feared against the resistor.
Please perform adjustments to equipment and so on, not to apply strong shock against resistor.
Moreover, please avoid drop from high position.
6) Forming of lead wire
When bending lead wire, please do not apply strong force to the resistor and the welding section of
the lead-wire.
Please be careful for bending form of the lead wire, not to become unnatural curvature.
7) Environment influencing substance
The resistor does not use class 1 ozone-depleting substance and specific bromine system
flame-resisting agent (PBBO's, PBB's etc.). This includes direct content and use at process.
8) Others
This specification expresses quality, performance of the electronic part alone in single. For use at
your company, please be sure to carry out evaluation and check in the state where it is mounted
in your product.
These parts have the intention of being used by the general electric devices. In case that
possibility of serious influence by the fault of these parts may be feared by the use to other
devices requiring high reliability (traffic transport machine, medical apparatus, electric heat,
combustion, gas apparatus, rotation apparatus, disaster prevention apparatus, etc.), please give
extra consideration in design such as protection circuit, protection equipment, redundant circuit,
etc. and secure safety of equipment.
