* Contact factory for values other than E12

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” on 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.
