Procurement Notes

Verify the specific suffix 'LFTR' against the manufacturer's official datasheet to confirm tape and reel packaging requirements. Ensure the ordered quantity aligns with the specified minimum order multiples provided by the supplier. Cross-reference the RoHS compliance status with the latest environmental documentation before finalizing procurement.

Selection Notes

Select this component for designs requiring high efficiency and rugged performance in low-cost applications. The dual-coil architecture allows it to function as two single inductors or a transformer. Verify that the required inductance values match the series or parallel connection options available with this specific part number.

Part Context

This component belongs to the HM78D series of shielded surface mount inductors from BI Technologies. The series is designed for applications demanding high inductance and excellent current handling. These parts are commonly utilized in portable electronics such as digital cameras, GPS systems, and mobile devices due to their compact form factor and reliability.

Replacement Considerations

Check for direct substitutes within the HM78D series with different inductance values if electrical parameters do not match. Verify pin compatibility and physical dimensions before considering alternative manufacturers.
