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 terminal 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.

If any questions arise whether to use the “Rated Ambient Temperature” or the “Rated Terminal Part Temperature” in your usage condi-
tions, please give priority to the “Rated Terminal Part Temperature.”
Prior to use and for more details, please refer to the “Introduction of the derating curves based on the terminal part temperature” in the
beginning of our catalog.
