When a fault pushes the current past the 3.5 A trip threshold (It), the device heats up and switches to a high-resistance state in 1.5 seconds typical, limiting the fault current to 100 A max. After the fault clears and power cycles, it resets — no fuse replacement needed. The 18 mOhm initial resistance (Ri min) keeps I²R losses low during normal operation; after tripping, the resistance rises to 80 mOhm max (R1 max) to hold the high-impedance state. ## Package and board-fit for 1206 reflow assembly The concave termination allows visual solder-joint inspection after reflow. The device carries cURus and TUV approvals, confirming compliance with North American and European safety standards for polymeric PTCs.","metaTitle":"Littelfuse 1206L200PR PTC Resettable Fuse, 2A Hold, 6V","metaDescription":"Active Littelfuse 1206L200PR POLY-FUSE polymeric PTC resettable fuse, 2A hold current, 6V max, 100A max fault. cURus, TUV approved.
