If any questions should 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.

For resistors operated at an ambient temperature
of 70°C or above, a power rating shall be derated
in accordance with the above 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.
