Procurement Notes

Verify the specific ordering suffix to ensure correct inductance and tolerance specifications. Confirm RoHS compliance status as required by project standards. Check current availability as the part may be subject to discontinuation or phase-out notices from the manufacturer.

Selection Notes

Select this component for applications requiring through-hole mounting and high common mode inductance. Ensure the PCB layout accommodates the 16.0 x 18.0 mm case size and vertical pin configuration. Verify that the 800 mA current rating meets the circuit requirements.

Part Context

This component belongs to the LH series of power inductors produced by Taiyo Yuden. The series utilizes a wound chip inductor structure inherited from axial lead types, offering high quality and mass production efficiency. The design emphasizes durability through heat-resistant molding processes.

Replacement Considerations

Taiyo Yuden lists this part as being in Phaseout status. Engineers should identify alternative components from the same manufacturer's portfolio or compatible third-party equivalents that match the 4400 uH common mode inductance and 800 mA current specifications.
