Terminal Part Temperature
(°C)
For resistors operated at an ambient temperature of 85°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 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.

The maximum applicable voltage is equal to the max. overload
voltage. Please ask us about the resistance characteristic of
continuous applied pulse. The pulse endurance values are not
assured values, so be sure to check the products on actual
equipment when you use them.
