For resistors operated at an ambient temperature
of 70°C or above, a power rating shall be derated
in accordance with the above derating curve.
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 above derating curve.
Please refer to “Introduction of the derating curve based on the terminal part
temperature” in the beginning of our catalog before use.
