A power rating is guaranteed at the terminal part temperature
If any questions should arise whether to use the “Rated Ambient Temperature” or the “Rated Terminal Part Temperature,” please give
priority to the “Rated Terminal Part Temperature.” Prior to use and for more details refer to “Introduction of the derating curves on the
terminal part temperature” in the beginning of the catalog.

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” in the beginning of
our catalog before use.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
