Derating Curves
For resistors operated at an ambient temperature of 70C or above, power rating shall be derated according to the ambient temperature derating curve. For resistors operated at a terminal part temperature of described for each size or above, power rating shall be derated according to the terminal part temperature derating curve. Prioritize the "Rated Terminal Part Temperature" if there are questions. Refer to the catalog for detailed introduction of derating curves.
