Rated voltage＝ Power Rating×Resistance value or Max. working voltage, whichever is lower.
※1 If you use at the rated power, please keep the condition that the terminal of the resistor is below the rated terminal part temperature. Please refer to the derating curves based on the terminal
temperature of right side on the next page.

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