It can interrupt a fault up to 50 A, which covers most low-voltage power sources; the 1 s trip time at 8 A (the trip current) keeps downstream silicon from cooking during a sustained overcurrent. ## Resistance budget and series positioning Initial resistance is 5 mOhms minimum, rising to 40 mOhms max after a trip event — the LoRho (low-resistance) formulation keeps I²R losses under 20 mW at 2 A, so the part doesn't heat the board noticeably during normal operation. ## Temperature range and approvals Carries cURus and TUV approvals, which cover North American and European equipment safety requirements for overcurrent protection components.","metaTitle":"0603L200SL-VYR Littelfuse PTC Resettable Fuse, 2 A Hold, 6 V","metaDescription":"0603L200SL-VYR Littelfuse POLY-FUSE LoRho PTC resettable fuse, 2 A hold current, 6 V max, 50 A max fault, 0603 package.
