1812L200THPR Description

Short technical summary and product information.

The Littelfuse 1812L200THPR is a PolySwitch resettable PPTC (Polymeric Positive Temperature Coefficient) overcurrent protection device. It is designed for surface mount applications where resettable protection is desired, eliminating the need for fuse replacement after a fault.

 

Key electrical specifications include a hold current of 2 A, a trip current of 3.5 A, a maximum voltage of 8 V, and a maximum interrupt current of 100 A. Typical power dissipation is 0.8 W. The device features a low initial resistance of 0.02 Ω and a maximum post-trip resistance of 0.07 Ω, with a fast trip time of 2 seconds at 8 A.

 

The 1812L200THPR is housed in a compact 1812 (4532 Metric) concave surface mount package measuring 4.55 mm x 3.24 mm x 0.60 mm. It is RoHS compliant, lead-free, and halogen-free, making it suitable for environmentally conscious designs. The operating temperature range is -40°C to 85°C.
