• Point-of-load regulation stages

Procurement Notes

Verify the specific suffix LFTR13 against official manufacturer documentation to confirm reel quantity and tape specifications. Confirm availability status as distribution channels may list discontinued or limited stock items. Ensure the ordering part number matches the exact electrical parameters required for the target application circuit design.

Selection Notes

Select this component when designing for high-current automotive environments requiring robust thermal performance up to 155°C. The unshielded design necessitates careful PCB layout to manage electromagnetic interference. Compare saturation current requirements against peak load conditions to ensure stable operation without magnetic saturation during transient events.

Part Context

This part belongs to the HA72E series of high-performance molded power inductors. The series is characterized by low DC resistance and high current handling capabilities. It is designed for surface-mount assembly processes, providing a compact solution for space-constrained electronic designs requiring reliable inductive components.

Replacement Considerations

Official direct substitutes are not confirmed in public documentation. Evaluate cross-reference options based on matching inductance, current ratings, and package dimensions. Verify that any alternative component meets the same AEC-Q200 qualification if automotive compliance is mandatory.
