For resistors operated at an ambient temperature
of 70°C or above, a power rating shall be derated
in accordance with the 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 derating curve.
Please refer to “Introduction of the derating curve based
on the terminal part temperature” in the beginning
of our catalog before use.
