Procurement Notes

Verify the manufacturer designation as API Delevan or Delevan when sourcing. Confirm RoHS compliance status through official documentation, as sources indicate varying declarations. Ensure the specific part number matches the required 47 uH inductance and 76 mA current rating to avoid functional mismatches in RF circuits.

Selection Notes

Select this component for applications requiring a 47 uH inductance with tight 5 percent tolerance. Consider the 8.2 ohm DC resistance and 76 mA current limit during thermal and power budgeting. The unshielded design requires careful layout consideration to prevent magnetic interference with nearby sensitive components.

Part Context

This component belongs to the Delevan 0819 series of fixed RF inductors. These parts are characterized by their molded unshielded coils and axial leads. The series offers various inductance values tailored for radio frequency environments, providing reliable performance for impedance matching and filtering tasks in electronic assemblies.

Replacement Considerations

Cross-reference with other 47 uH axial RF inductors having similar current ratings and physical dimensions. Verify that substitute components meet the 11.5 MHz self-resonant frequency requirement and maintain comparable Q factors for equivalent circuit behavior.
