Derating Curve
For resistors operated at an
ambient temperature of 70°C or
above, a power rating shall be
derated in accordance with the
above derating curve.
For resistors operated at a terminal part
temperature of described for each size or
above, a power rating shall be derated in
accordance with the above derating curve.
Please refer toIntroduction of the derating
curve based on the terminal part temperature
in the beginning of our catalog before use.

Regarding the temperature rise, the value of the temperature
varies per conditions and board for use since the temperature
is measured under our measuring conditions.
The maximum applicable voltage is equal to the max. overload voltage. Please
ask us about the resistance characteristic of continuous applied pulse. The pulse
endurance values are not assured values,so be sure to check the products on
actual equipment when you use them.
