With a 5 A hold current (Ih) and a maximum interrupt current of 50 A, it trips in 2 seconds under fault conditions, then resets when power is removed and the device cools. The LoRho variant keeps initial resistance at a minimum of 1 mOhm and post-trip resistance at a maximum of 12 mOhm, minimising I²R losses in normal operation — critical for battery-powered or high-efficiency designs. ## Package, approvals, and operating range Approved by cURus and TUV, it carries the key safety certifications for North American and European markets.","metaTitle":"Littelfuse 1206L500/12SLPR PTC Resettable Fuse, 5A Hold, 12V","metaDescription":"Littelfuse 1206L500/12SLPR POLY-FUSE LoRho PTC resettable fuse, 5A hold current, 12V max, 1206 SMD.
