If any questions arise whether to use the “Rated Ambient Temperature” or the 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 Temperature Rise (°C)21543000000 10 20 30 40Pow5e0r Ra6t0ing7 0 80 90 10011111111JEJEHFHF Temperature Rise (°C)142860000000 10 20 30 40Pow5e0r Ra6t0ing7 0 80 90 100222222EEBABA One-Pulse Limiting Electric Power (W) 010.001.01101.001 .01 .1 1 10 100 100211110AJEHF One-Pulse Limiting Electric Power (W) 1010010100.001 .01 .1 1 10 100 100W2220HEB3/AW/W2H3A2 (%) (%) Pulse Duration RK73H W2H-W3A2 (ms) Regarding the temperature rise, the value of the temperature varies 300 The maximum applicable voltage is equal to the max. overload supinendrc eceor tnohdueir tt ieommnespa aesunrarditn ubgroe ca iors dn m dfoietriao usnsuser.ed Temperature Rise (°C)21125500500000 WWWWWW333232AAAHAH22 MRPCCoueo Bafmos: iuFl trtReehmm-ic4pket nen= ert a 1 sc t s.ou6:nr me3①d:5m i t:2µi o H5mn°oC t s pot② :Terminal vcaeoosqlnsutautiipgnremeud.oe Puvnsatle lwuaaephsspee,ln iaes ysdook pb uuue sul s ssaeueb.r eotTh uhteote m t hcp.heue lrsceeks ietshntead nupcrreao ndccuheca trvsaa oclutnee rasisc attiucrea o lnfot 0 10 20 30 40 50 60 70 80 90 100 Performance Characteristics Powe(r% R)ating Requirement ∆ R (%+0.1Ω) Parameter Limit Typical Test Method Resistance Within specified tolerance — 25°C T.C.R.
