POLY-FUSE®, 1206L series, Type Polymeric, PTC Resettable Fuse, 1206 (3216 Metric) Concave package, 60V max, 100 mA hold current, AEC-Q200 qualified.","salesMarkdown":"## Hold current and trip threshold for the BOM line The 1206L010/60WR-A is a Littelfuse POLY-FUSE polymeric PTC resettable fuse in the 1206L series, rated for a maximum voltage of 60V and a maximum current of 10A. Its hold current (Ih) is 100 mA, meaning the device will not trip below that steady-state current under normal ambient conditions. The trip current (It) is 250 mA — once the fault current reaches this level, the PTC heats up and its resistance jumps, limiting the current to protect downstream circuitry. ## Time-to-trip and resistance profile At 25°C, the typical time to trip is 1.5 seconds when the fault current is high enough to trigger the PTC. The initial resistance (Ri) is at least 1.5 ohms, and after tripping the post-trip resistance (R1) rises to a maximum of 10 ohms. This resistance shift is what holds the circuit in a high-impedance state until power is cycled and the PTC cools back to its low-resistance state. ## Automotive-grade qualification and approvals It also holds cURus and TUV approvals, covering North American and European safety standards for overcurrent protection devices. It is a surface-mount component supplied on tape and reel or cut tape, suitable for reflow soldering.","metaTitle":"Littelfuse 1206L010/60WR-A PTC Resettable Fuse, 60V","metaDescription":"Littelfuse 1206L010/60WR-A POLY-FUSE polymeric PTC resettable fuse, 60V max, 100mA hold current, AEC-Q200 qualified.
