Procurement Notes

Verify the specific manufacturer designation, as API Delevan assets are often managed by other entities. Confirm RoHS compliance status directly with the supplier, as historical data indicates variations across the product line. Ensure the ordering suffix matches the required tolerance and packaging configuration for your production needs.

Selection Notes

Select this component when a 27 µH inductance value is required for RF signal paths. Consider the 100 mA current limit and 4.7 Ohm resistance for power handling requirements. The unshielded design necessitates careful layout to prevent magnetic coupling with adjacent components in dense PCB assemblies.

Part Context

This part belongs to the Delevan 0819 series of fixed RF inductors. The series offers various inductance values with tight tolerances, utilizing a consistent physical footprint. These components are engineered for high-frequency performance, providing stable electrical characteristics suitable for demanding radio frequency environments.

Replacement Considerations

The 0819R-58G serves as a functional equivalent with similar electrical specifications. Verify that substitute parts maintain the same axial package dimensions and lead spacing to ensure mechanical compatibility during installation.
