Procurement Notes

Verify the manufacturer part number against official Delevan documentation to confirm exact electrical parameters. Ensure the specific suffix matches the required tolerance and current rating. Cross-reference datasheets for thermal limits and mounting orientation requirements before integration into final designs.

Selection Notes

Select this component when an unshielded axial inductor is required for RF frequencies around 100 MHz. Consider the 236 mA current limit and 0.85 Ω resistance for power handling. Compare physical dimensions against available PCB space. Evaluate alternative values within the 0819 series if different inductance or current specifications are needed.

Part Context

This component belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with axial leads and molded bodies. These parts are designed for general-purpose radio frequency applications requiring reliable performance in unshielded environments.

Replacement Considerations

Consult official Delevan substitution guides for direct equivalents. Verify that any substitute maintains the 2.7 µH inductance, 5% tolerance, and 236 mA current rating. Ensure physical footprint compatibility for axial mounting.
