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.
