Procurement Notes

Verify the obsolete status of this part number before procurement planning. Confirm RoHS compliance requirements as historical data indicates non-compliance. Check for valid substitute components from the same manufacturer series to ensure supply chain continuity for existing designs.

Selection Notes

Select this component for designs requiring precise 2.7 µH inductance in compact SMD footprints. Ensure the operating current remains below the 230 mA rating to maintain performance. Verify that the unshielded nature does not cause interference in dense PCB layouts.

Part Context

This component belongs to the Delevan 106 series of fixed RF inductors. These parts are characterized by their small surface-mount form factor and high stability. They are designed specifically for radio frequency signal processing tasks where size and precision are critical constraints.

Replacement Considerations

Consult official Delevan documentation for confirmed cross-reference part numbers. Do not assume functional equivalence with other series without verifying electrical parameters and physical dimensions.
