Terminal Part Temperature
(°C)
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.
