Derating Curve
For resistors operated at an ambient temperature of 85C or above, or at a terminal part temperature described for each size or above, power rating shall be derated in accordance with the derating curve.
Note: Prioritize "Rated Terminal Part Temperature" over "Rated Ambient Temperature" if there are any questions.
