The Littelfuse PolySwitch 1812L050PR is a polymeric positive temperature coefficient (PPTC) resettable fuse designed for overcurrent protection in a wide range of electronic circuits. It provides automatic reset after fault conditions are cleared, eliminating the need for replacement fuses.
The device is rated for a hold current of 500 mA and a trip current of 1 A at a maximum voltage of 15V DC. It can withstand fault currents up to 100 A. Typical power dissipation is 0.8 W. Initial resistance is as low as 0.15 Ω, rising to a maximum of 1 Ω after tripping. The time to trip at 8 A is 150 ms.
The 1812L050PR is housed in a compact 1812 (4532 Metric) concave surface mount package, measuring 4.55 mm in length, 3.24 mm in width, and 0.75 mm in thickness. It operates over a temperature range of -40°C to +85°C. The component is RoHS compliant, lead-free, and halogen-free, suitable for high temperature soldering processes.
The hold current is 500 mA.
The maximum voltage is 15V DC.
It uses an 1812 (4532 Metric) concave surface mount package.
The trip current is 1 A.
The operating temperature range is -40°C to +85°C.
