Procurement Notes

Verify the specific datasheet version to confirm electrical tolerances and thermal ratings prior to integration. Ensure the ordering suffix matches the required packaging format, as variations may exist between bulk reels and tape-and-reel configurations. Cross-reference the manufacturer's latest compliance documentation to confirm material specifications and environmental restrictions relevant to the production batch.

Selection Notes

Select this component when an 8.2 µH inductance value is required within a compact axial form factor. The unshielded design necessitates careful layout planning to minimize electromagnetic interference with adjacent traces. Verify that the operating current remains below the 104 mA rating to prevent saturation or thermal issues in the target application environment.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series utilizes molded construction techniques to provide consistent electrical characteristics across production batches. These components are engineered specifically for high-frequency applications where stable inductance and low parasitic effects are critical for circuit performance.

Replacement Considerations

The 0819R-46K is a documented substitute variant within the same product family. Both parts share identical electrical parameters including 8.2 µH inductance and 10% tolerance. Verify mechanical footprint compatibility before substitution.
