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
3A
above, a power rating shall be derated in
(2512)
accordance with the above derating curve.
Please refer to “Introduction of the derating
W3A/W3A2
curve based on the terminal part temperature”

If any questions arise on whether to use the “Rated Ambient Temperaute” or the “Rated Terminal Part Temperature” in your usage conditions, please give priority to the “Rated
Terminal Part Temperature.” Prior to use and for more details, refer to “Introduction of the derating curves based on the terminal part temperature” in the beginning of our catalog.
Temperature rise at high power will depend on PCB layout. Be sure to contact factory prior to use and monitor terminal part temperature.
