2920L125PR Description

Short technical summary and product information.

The Littelfuse 2920L125PR is a polymeric PTC resettable fuse from the 2920L series, designed for surface mount overcurrent protection. It provides resettable protection in medium voltage applications, with a maximum voltage rating of 15V DC.

 

Key electrical specifications: hold current 1.25A, trip current 2.5A, maximum fault current 40A, and typical power dissipation 1.5W in tripped state. Initial resistance is minimum 70 mΩ, and post-trip maximum resistance is 250 mΩ. Time to trip at 8A is 2 seconds maximum.

 

Package: surface mount 2920 (7351 metric) concave package. Operating temperature range -40°C to 85°C. RoHS compliant (unverified), MSL 1 (unlimited). Compliance data should be verified against manufacturer documentation.

 

Suitable for overcurrent protection in low-voltage DC circuits where resettable protection is required. The compact 2920 package is ideal for space-constrained designs.
