POLY-FUSE® 1206L series, Polymeric PTC Resettable Fuse, 1206L110THYR, 1.1A hold, 2.2A trip, 8V max, 100 ms trip time, surface mount 1206.","salesMarkdown":"## Hold current and trip threshold The 1206L110THYR is a Littelfuse POLY-FUSE polymeric PTC resettable fuse in the 1206L series. It holds 1.1 A continuously without tripping; once the fault current exceeds 2.2 A (the trip current), the polymer heats and the resistance jumps from a typical 40 mOhms initial to as high as 210 mOhms post-trip, limiting the current within 100 ms (typical). ## Voltage and current limits Rated for a maximum voltage of 8 V and a maximum fault current of 100 A — the device can interrupt a short-circuit up to that current without rupturing, as long as the supply rail stays at or below 8 V. ## Temperature range and approvals Approved by cURus and TUV, so it is accepted in North American and European safety-certified designs without additional agency review. Supplied on tape and reel or cut tape — the concave body suits standard pick-and-place and reflow assembly.","metaTitle":"1206L110THYR Littelfuse PTC Resettable Fuse, 1.1A Hold, 8V","metaDescription":"Littelfuse 1206L110THYR POLY-FUSE polymeric PTC, 1.1A hold current, 2.2A trip, 8V max, 100ms trip time.
