Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with automated placement equipment if reel packaging is required. Cross-reference datasheet revisions to confirm material compliance and RoHS status prior to final procurement decisions.
Selection Notes
Select this component when high inductance values are required in a compact axial form factor. The 1% tolerance suits precision tuning applications. Evaluate the low self-resonant frequency constraint to ensure suitability for the target operating band. Confirm that the 27 mA current rating meets the circuit's DC bias requirements without saturation.
Part Context
This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values in a consistent molded axial package. These components are designed for general-purpose RF use where unshielded performance is acceptable. The 0819-92F represents the higher inductance end of the standard range within this family.
Replacement Considerations
Consult official substitution guides for equivalent axial RF inductors. Verify that any alternative part matches the 680 µH value, 1% tolerance, and physical dimensions. Ensure the replacement maintains similar Q factor and self-resonant frequency characteristics for circuit stability.
