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. *1 If you want to use the rated power of *1, please use the
derating curve based on the terminal part temperature on the right hand side.

arise whether to use the “Rated Ambient Temperature” or the “Rated Terminal Part Temperature,” please give priority to the “Rated Terminal Part Temperature.” Prior to
use and for more details refer to “Introduction of the derating curves on the terminal part temperature” in the beginning of the catalog. *1 If you want to use the rated
