POLY-FUSE® 1206L series PTC resettable fuse, 1206L035YR, 350 mA hold, 750 mA trip, 6V max, 100 ms trip time, surface mount 1206 (3216 Metric) concave package, Tape & Reel.","salesMarkdown":"## 350 mA hold, 6V max — POLY-FUSE 1206L PTC resettable fuse The Littelfuse 1206L035YR is a polymeric PTC resettable fuse from the POLY-FUSE 1206L series, rated for 350 mA hold current (Ih) with a 750 mA trip current (It) and a maximum voltage of 6V. It resets after a fault clears — no fuse replacement needed on the board, which saves a service call on a sealed assembly. The 1206 (3216 Metric) concave package sits at 0.030\" (0.75 mm) thick, surface-mount, and the 100 ms typical trip time at 100 A max fault current means it clears fast enough to protect downstream traces and connectors in a low-voltage rail. ## Active production — no obsolescence watch needed The approvals — cURus and TUV — cover North American and European safety agency acceptance, so the same reel clears both UL and IEC-based equipment certifications without a component change. ## Sourcing and compliance Operating temperature range is -40°C to 85°C, covering most indoor and outdoor equipment enclosures. Initial resistance (Ri) is 300 mOhms minimum, rising to 1.2 Ohms max after a trip event — the post-trip resistance is the figure to budget for voltage drop in the faulted state.","metaTitle":"1206L035YR Littelfuse PTC Resettable Fuse, 350 mA, 6V, 1206","metaDescription":"Littelfuse 1206L035YR POLY-FUSE PTC resettable fuse, 350 mA hold current, 6V max, 100 ms trip time.
