The 1812L020PR is a PolySwitch resettable PPTC (Positive Temperature Coefficient) fuse from Littelfuse's 1812L series. It provides surface mount overcurrent protection for applications where resettable protection is desired. The device automatically resets after the fault is cleared, eliminating the need for fuse replacement.
Key electrical specifications include a hold current of 200 mA, a trip current of 400 mA, a maximum operating voltage of 30V DC, and a maximum fault current capability of 100A. The typical time to trip at 8A is 20 ms, enabling fast response to overcurrent conditions. The minimum resistance is 0.8Ω and the maximum resistance after tripping is 5Ω. Typical power dissipation is 0.8W.
The 1812L020PR comes in a compact 1812 (4532 Metric) concave surface mount package measuring 4.55mm x 3.24mm with a maximum thickness of 1.00mm. It is designed for a wide operating temperature range of -40°C to 85°C. The device is RoHS compliant, lead-free, and halogen-free as verified by the manufacturer's datasheet.
