Rated voltage = Power rating x resistance value or max. working voltage, whichever is lower 1F: 10~2M: E-24. 1H: 1.0~9.1, 1M~10M: E-24. If any questions 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 based on the terminal part temperature in the beginning of the catalog.
environmental applications While using under high power, the temperature of the product may increase depending on the condition of heat dissipation from
PCB. Be sure to check the terminal part temperature as well as precautions to use on delivery specification before use.
