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 derating curve.
Please refer to “Introduction 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.
Please contact factory prior to use.
