• High-frequency signal conditioning

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging configuration, as variations may exist between bulk and reel formats. Confirm RoHS compliance status, as some variants in this series are non-compliant. Cross-reference the manufacturer part number with distributor catalogs to validate availability and lead times. Ensure the selected unit matches the required inductance tolerance and current rating for the target application.

Selection Notes

Select this component when a compact, unshielded axial inductor is required for RF frequencies near 590 MHz. Consider the 420 mA current limit and 590 mΩ resistance for power handling requirements. Compare against other 0819 series values if different inductance or tolerance specifications are needed. Verify that the physical dimensions fit the available PCB real estate.

Part Context

This component belongs to the Delevan 0819 series of general-purpose RF inductors. These parts are characterized by their molded construction and axial leads, distinguishing them from surface-mount alternatives. The series offers various inductance values tailored for radio frequency applications, providing a standardized form factor for consistent assembly processes.

Replacement Considerations

Direct substitutes include the 0819R-14H, which shares identical electrical parameters but differs in RoHS compliance status. Other 0819 series variants offer similar mechanical footprints but require verification of inductance and current ratings before substitution.
