The component has a maximum DC resistance of 3.2 Ω and supports a maximum DC current of 122 mA. Designed for PCB mounting via axial leads, it offers a minimum Q factor of 30 and a self-resonant frequency of 440 MHz. Physical dimensions are 5.08 mm in length and 1.98 mm in diameter.

Feature Summary

• Molded unshielded coil design for RF applications
• Axial lead termination for through-hole PCB mounting
• High precision ±1% inductance tolerance

Applications

• RF circuit filtering
• Impedance matching networks
• General purpose RF signal processing

Procurement Notes

Verify the specific manufacturer designation, as sources list both API Delevan Inc. and Delevan. Confirm RoHS compliance status, as documentation indicates non-compliance (N). Ensure the ordering suffix matches the required tolerance and packaging format. Cross-reference datasheets to confirm electrical parameters against the specific production batch requirements.

Selection Notes

Select this component for applications requiring high-precision inductance values in the RF spectrum. The unshielded design necessitates careful layout consideration to minimize electromagnetic interference with adjacent components. Verify that the 122 mA current rating aligns with the operational load to prevent saturation or thermal issues.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. These components are characterized by their molded construction and axial lead configuration, distinguishing them from surface-mount alternatives. The series is engineered for reliability in radio frequency environments where stable inductance is critical.

Replacement Considerations

The 0819R-44F is a documented variant within the same series, sharing identical electrical specifications including 6.8 µH inductance, 1% tolerance, and 3.2 Ω resistance. Verify package compatibility before substitution.
