If any questions arise whether to use the Rated Ambient Temperature or the Rated voltage = Power rating x resistance value or max. working voltage, whichever is lower 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. 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. environmental applications Temperature Rise One-Pulse Limiting Electric Power RK73H 1F-1J RK73H 2A-2E RK73H 1F-2A RK73H 2B-W3A2 100 1000 50 100 2E 40 1J 80 2E 10 1E 2B 1J 2A 100 30 1E 60 2B 1H 2A 1F 1 20 40 1H 2A 1J 1F 1E W3A/W3A2 10 1H 10 20 2H/W2H 1F 2E 0.1 2B 0 0 10 20 30540060 70 80 90 100 10 20 30540060 70 80 90 100 1 0.01 .001 .01 .1 1 10 100 1000 .001 .01 .111 1000 1000 Power Rating Power Rating (%) (%) Pulse Duration (ms) RK73H W2H-W3A2 Regarding the temperature rise, 300 the value of the temperature varies The maximum applicable voltage is equal to the max. overload W3A2 250 per conditions and board for use voltage.
