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.
Circuit Board Application
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
