Fixed Inductors Procurement Notes

Verify RoHS compliance status as military variants may differ. Confirm package type (bulk vs reel) matches assembly requirements. Check lead time availability due to specialized manufacturing. Ensure axial lead dimensions fit PCB layout constraints.

Fixed Inductors Selection Notes

Select this part for high-frequency RF applications requiring precise 3% tolerance. Consider the 125 mA current rating for power handling limits. Verify thermal performance within the -55°C to 105°C range. Compare DCR and Q factor against circuit impedance requirements.

Fixed Inductors Part Context

Part of the Delevan 1025R series, offering reliable performance for electronic systems. The 1025R designation indicates specific molding and core characteristics distinct from other series like ER1025 or standard 1025 models.

Fixed Inductors Replacement Considerations

Check 1025R-58K for ±10% tolerance variant. Verify ER1025-58KR for military specification equivalent if required.
