The Littelfuse 1812L150ZR is a PolySwitch resettable PPTC (polymeric positive temperature coefficient) overcurrent protection device designed for surface mount applications. It provides resettable protection for circuits where a one-time fuse would require replacement.
Key electrical specifications include a hold current of 1.25 A, a trip current of 2.5 A, and a maximum voltage rating of 8 V DC. The device can handle a maximum interrupt current of 100 A and dissipates 0.8 W of power. Typical initial resistance is 0.11 Ω, with a minimum initial resistance of 0.05 Ω and a maximum post-trip resistance of 0.14 Ω. Trip time is 300 ms at 8 A.
The 1812L150ZR is housed in an 1812 (4532 Metric) concave surface mount package measuring 4.55 mm by 3.24 mm with a thickness of 1.25 mm. It operates over a temperature range of -40°C to 85°C. The datasheet reports compliance with RoHS, lead-free, and halogen-free requirements.
The hold current is 1.25 A at 25°C.
The trip current is 2.5 A.
The maximum voltage rating is 8 V DC.
The typical time to trip is 300 ms at an 8 A fault current.
It is available in a surface mount 1812 (4532 Metric) concave package.
