Procurement Notes

Verify RoHS compliance status as sources indicate conflicting data (compliant vs non-compliant). Confirm exact electrical parameters against the official datasheet before integration. Ensure the supplier provides the correct reel packaging quantity specified by the manufacturer.

Selection Notes

Select this component for designs requiring a 20 µH coupled inductor with high current handling capabilities. The 2.1 A rating and low DCR make it suitable for power management stages where space efficiency is critical due to its SMT form factor.

Part Context

This part belongs to the Delevan 4448 series of power inductors. These components are characterized by their toroidal core structure and high current density. The series is widely used in industrial and commercial electronics for efficient power conversion.

Replacement Considerations

Check for equivalent parts within the same series or similar specifications from other manufacturers. Verify pinout compatibility and physical dimensions to ensure direct replacement without PCB redesign.
