1210L150THWR Description

Short technical summary and product information.

The Littelfuse 1210L150THWR is a PolySwitch PTC resettable fuse from the 1210L series, designed for surface mount overcurrent protection in space-constrained applications. It has a hold current of 1.5 A and a trip current of 3.0 A at 20°C still air, with a maximum voltage rating of 6 V and a maximum interrupt current of 100 A. Typical power dissipation is 0.8 W.

 

The device trips in 300 ms at 8.0 A and offers low resistance: initial minimum resistance of 40 mΩ and post-trip maximum resistance of 110 mΩ. It is housed in a 1210 (3225 Metric) concave surface mount package measuring 3.22 mm x 2.58 mm x 1.07 mm.

 

This Polymeric PTC is suitable for overcurrent protection in compact electronic designs where resettable protection is required. Operating temperature range is -40°C to 85°C. The part is RoHS compliant, lead-free, and halogen-free.
