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 RK73H W2H-W3A2 100 1000 100 300 60 2E 1E 90 W3A2 1J 250 50 80 2E 1E W3A2 10 1J 70 2B 200 100 40 1H 2A W3A 1F 60 2A W3A/W3A2 2B 1H W2H 150 1 30 50 1J 1F 2A W3A 40 2H/W2H 1E 100 10 20 W2H 30 0.1 1H 20 2E 50 10 1F 10 2B 0 0 0 0.01 1 0 25 50 75 100 0 25 50 75 100 0 25 50 75 100 0.001 0.01 0.1 1 10 100 1000 0.001 0.01 0.1 1 10 100 1000 Power Rating Power Rating Power Rating Pulse Duration (%) Pulse Duration (%) (%) (ms) (ms) Measurement condition The maximum applicable voltage is equal to the max. overload voltage.
