The Littelfuse 1812L050PRT is a PolySwitch resettable PPTC (positive temperature coefficient) overcurrent protection device from the 1812L series. It is designed for surface mount applications where resettable protection is required, eliminating the need for replacement after a fault event.
Key electrical specifications include a hold current of 500 mA, a trip current of 1 A, a maximum voltage rating of 15 V DC, and a maximum interrupt current of 100 A. Typical power dissipation is 0.8 W. The device has an initial resistance of 150 mΩ and a post-trip resistance of 1 Ω. The time to trip at 8 A is 150 ms.
The 1812L050PRT is housed in a standard 1812 (4532 metric) concave surface mount package with dimensions of 4.55 mm length, 3.24 mm width, and 0.75 mm thickness. It operates over a temperature range of -40°C to 85°C. The device is RoHS compliant, lead-free, and halogen-free per the manufacturer's datasheet.
The hold current is 500 mA (0.5 A).
The maximum voltage is 15 V DC.
The trip current is 1 A.
The package is 1812 (4532 Metric), concave surface mount.
The operating temperature range is -40°C to 85°C.
The time to trip at 8 A is 150 ms.
The datasheet states RoHS compliance, but this has not been independently verified.
