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.
