Its initial resistance (Ri) is just 5 mOhms minimum, rising to 25 mOhms maximum after a trip event (R1) — the LoRho series is engineered to minimize voltage drop in high-current paths like USB VBUS or battery-charger outputs. ## Trip characteristics and overcurrent response The device trips at 4 A (It) and clears within 500 ms typical under fault, limiting the energy delivered to the protected load before the polymer returns to its low-resistance state. ## Approvals and compliance signal The 1206L200SLYR carries cURus and TUV agency approvals, marking it accepted for North American and European equipment safety certification.","metaTitle":"Littelfuse 1206L200SLYR PTC Resettable Fuse, 2A Hold, 6V","metaDescription":"Littelfuse POLY-FUSE LoRho 1206L200SLYR polymeric PTC resettable fuse, 2A hold current, 6V max, 5 mOhm initial resistance.
