Procurement Notes
Verify the specific datasheet version to confirm RoHS compliance status, as documentation indicates variations across the series. Ensure that the axial lead length and overall physical dimensions align with the target printed circuit board layout constraints before finalizing the procurement order.
Selection Notes
Select this component when a fixed 3.9 µH inductance is required for RF signal paths. The unshielded design necessitates careful placement to minimize electromagnetic interference with adjacent components. Verify that the operating current remains below the 165 mA limit to prevent saturation or thermal issues.
Part Context
This part belongs to the Delevan 0819 series of leaded RF inductors. These components are characterized by their molded construction and axial leads, designed specifically for through-hole mounting on printed circuit boards within radio frequency electronic systems.
Replacement Considerations
The 0819R-38G serves as a potential substitute within the same product family. Verify that the R-series variant maintains identical electrical parameters and physical dimensions to ensure compatibility with existing designs.
