PerformanceCharacteristics

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.

Regarding the temperature rise, the value of the temperature

varies per conditions and board for use since the temperature

is measured under our measuring conditions.

±1.0% + 0.0001Ω

––

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.
