HM66-50680LFTR13

Overview

The HM66-50680LFTR13 is a surface-mount power inductor from the HM66 series, manufactured by TT Electronics/BI Magnetics. It features a wirewound core and shielded construction designed for high-current applications. The component has a nominal inductance of 68 µH with a tolerance of ±20%. Key electrical parameters include a maximum DC resistance of 355 mΩ and a rated current of 520 mA. The device operates within a temperature range of -40°C to +125°C and utilizes matte tin terminations. It is supplied in tape and reel packaging.

Feature Summary

Shielded wirewound construction for reduced electromagnetic interference
Surface-mount design optimized for automated PCB assembly
High thermal stability supporting operation up to 125°C

Applications

DC-DC converter input/output filtering
Power supply output chokes
General-purpose power circuit energy storage

Procurement Notes

Verify component availability as this part may be discontinued or subject to lifecycle changes. Confirm that the supplier provides original manufacturer documentation matching the specific suffix LFTR13. Ensure the receiving facility handles ESD-sensitive components appropriately during storage and installation to maintain performance integrity.

Selection Notes

Select this component when a shielded 68 µH inductor with low DCR is required for space-constrained designs. The 520 mA rating suits moderate power levels. Compare against unshielded alternatives if magnetic field containment is not critical. Verify footprint compatibility with existing PCB layouts before finalizing the bill of materials.

Part Context

This part belongs to the HM66 series of fixed surface-mount power inductors. The series offers various inductance values and current ratings. The HM66-50680LFTR13 specifically denotes the 68 µH variant with standard packaging. It shares mechanical dimensions with other members of the family but differs in electrical characteristics based on winding specifications.
