Procurement Notes

Verify the specific suffix configuration when ordering, as variants such as 0819R-14F may exist within the same series. Confirm that the standard 0819-14F designation aligns with the required 390 nH value and 420 mA rating. Ensure compatibility with existing PCB footprints regarding axial lead spacing and overall component dimensions before finalizing procurement.

Selection Notes

Select this component for applications requiring precise low-inductance values in high-frequency environments. The unshielded design necessitates careful layout consideration to minimize electromagnetic interference with adjacent traces. Verify that the 420 mA current rating meets the operational requirements of the target circuit under maximum load conditions.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values ranging from nanohenries to microhenries, all sharing a consistent molded axial form factor. These components are engineered for general-purpose RF applications where compact size and reliable performance are prioritized over shielding capabilities.

Replacement Considerations

The 0819R-14F is a documented variant within the same product family. Verify if the 'R' suffix denotes a specific packaging or testing difference compared to the standard 0819-14F before substitution.
