Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as the specific unit may contain lead. Validate physical footprint compatibility during replacement planning. Request updated datasheets to ensure parameter accuracy against legacy documentation.

Selection Notes

Select this component for designs requiring precise 4.7 µH inductance in compact RF layouts. Ensure the 200 mA current rating meets circuit load demands. Verify that the unshielded design does not interfere with nearby sensitive components. Check availability constraints given the product lifecycle status.

Part Context

This part belongs to the Delevan 106 series of fixed RF inductors. It is designed for high-frequency stability and reliability in electronic assemblies. The series utilizes ferrite materials to achieve consistent electrical characteristics across temperature variations.

Replacement Considerations

The 106-472F is a documented substitute with identical electrical parameters but a tighter 1% tolerance. Verify pinout and dimensional compatibility before implementation.
