Terminal Part Temperature
(°C)
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.
