Ptc Resettable Fuses Procurement Notes

Verify the specific suffix 'A' in the part number 2920L260/33DR-A against procurement requirements, as it may indicate specific packaging or material compliance variations. Confirm RoHS 3 certification status and moisture sensitivity level (MSL 2A) compatibility with the intended reflow soldering profile. Ensure the selected supplier provides official datasheets matching the exact component designation.

Ptc Resettable Fuses Selection Notes

Select this component when a 2.6 A hold current and 33 VDC rating are required for space-constrained applications. The 2920 package offers a balance between current handling and footprint size. Consider the 3 W power dissipation capability for thermal management planning. Verify that the 75 mOhms initial resistance meets the system's voltage drop constraints during normal operation.

Ptc Resettable Fuses Part Context

This component belongs to the Littelfuse POLY-FUSE 2920L series of resettable fuses. The series is designed for overcurrent protection in compact electronics. The 2920L260/33DR-A variant specifically targets applications requiring higher current ratings within the 33 VDC voltage class, offering a reliable alternative to traditional fusible links in modern surface-mount designs.
