Application

ResistanceRange

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 derating curve.

Please refer to “Introduction of the derating

curve based on the terminal part temperature”

on the beginning of our catalog before use.
