When a fault pushes current past 1.5 A (the trip current), the polymer heats and switches to a high-resistance state, limiting the fault to 50 A max. The trip happens in 300 ms typical — fast enough to protect a USB port or battery line from a dead short without letting the trace fuse. ## Low-resistance LoRho — less voltage drop in the power path Initial resistance (Ri) is 17 mOhms minimum; post-trip resistance (R1) climbs to 180 mOhms max. The LoRho formulation keeps the series drop under 13 mV at 750 mA — a meaningful margin when the downstream rail is 3.3V or 1.8V and every millivolt counts. Surface-mount assembly with tape-and-reel or cut-tape options. Design the trip threshold with the derating curve in mind. ## Active production, cURus and TUV approved The part carries cURus and TUV approvals, covering North American and European equipment safety requirements for a resettable overcurrent protector.","metaTitle":"1206L075SLYR Littelfuse PTC Resettable Fuse, 750 mA, 6V","metaDescription":"1206L075SLYR Littelfuse POLY-FUSE LoRho PTC resettable fuse. 750 mA hold, 1.5 A trip, 6V max, 50 A max fault.
