2920L030DR-A

Ptc Resettable Fuses Overview

The Littelfuse 2920L030DR-A is a polymeric PTC resettable fuse rated for 60V maximum voltage and 0.3A hold current. It features a surface-mount 2920 (7351 metric) concave package with dimensions of 7.35mm length, 5.12mm width, and 1.25mm thickness. The device trips at 0.5A and withstands up to 40A fault current. Initial resistance is 15 mOhms minimum, with post-trip resistance maxing at 48 mOhms. It operates between -40°C and 85°C, holds UL and TUV certifications, and complies with RoHS 3 standards.

Ptc Resettable Fuses Feature Summary

Ultra-low internal resistance design minimizes voltage drop in sensitive circuits
Automatic resettable protection eliminates the need for manual replacement after fault events
Low profile construction allows for higher hold current density in compact board spaces

Ptc Resettable Fuses Applications

Overcurrent protection for IoT control units
General electronics circuit safeguarding
Building and home automation systems

Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'A' against the manufacturer's official documentation to confirm any distinct material or packaging variations compared to the standard 2920L030DR variant. Ensure compatibility with RoHS 3 compliance requirements and confirm moisture sensitivity level handling procedures during assembly to prevent package damage.

Ptc Resettable Fuses Selection Notes

Select this component when applications require overcurrent protection within a 60VDC system and demand minimal series resistance. The 0.3A hold current rating suits low-power signal lines. The 2920 surface-mount footprint is appropriate for automated assembly processes where space constraints necessitate a low-profile, high-current-density protective device.

Ptc Resettable Fuses Part Context

This part belongs to the Littelfuse POLY-FUSE® 2920L series, designed as a Low Rho SMD PolySwitch device. The series provides polymer positive temperature coefficient protection characterized by ultra-low internal resistance and fast response times. It serves as an alternative to traditional fuses in environments requiring automatic recovery from overcurrent conditions without interrupting system operation permanently.
