2920L030DR-A Description

Short technical summary and product information.

The Littelfuse 2920L030DR-A is a polymeric PTC resettable fuse from the 2920L series, designed for surface mount overcurrent protection in medium voltage applications up to 60V. Featuring a hold current of 0.3A and a trip current of 0.6A, it provides reliable resettable protection against overcurrent faults. The device can interrupt fault currents up to 10A and dissipates 1.5W typically.

 

Electrical characteristics include a maximum trip time of 3.0 seconds at 1.5A, initial resistance of 1.2Ω minimum, and resistance after trip of 4.8Ω maximum. The operating temperature range is -40°C to 85°C, making it suitable for a wide variety of environments.

 

The fuse is housed in a 2920 (7351 Metric) concave package with dimensions 7.36mm x 5.12mm and a maximum thickness of 1.25mm. It is surface mountable and RoHS3 compliant. Agency approvals are indicated in the datasheet, though specific agencies are not named.
