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 temperature” in the beginning of our catalog before use. If you want to use the rated power of *2, *3, please use the
derating curve based on the terminal part temperature on the right hand side.
