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