Procurement Notes

Verify the specific suffix (e.g., L) against official API Delevan documentation to confirm termination style and compliance status. Ensure the selected variant matches the required inductance tolerance and current ratings for the target application. Cross-reference datasheet revisions to confirm package dimensions and thermal characteristics before finalizing procurement specifications.

Selection Notes

Select this component when a dual-coil SMD inductor with 25 µH nominal value is required. Consider the 0.064 Ω DCR and 620 mA parallel current rating for power handling needs. Verify that the unshielded design aligns with EMI constraints and that the 13.71 x 13.71 mm footprint fits the board layout. Confirm RoHS compliance requirements match the specific suffix designation.
