Procurement Notes

Verify the specific suffix against official documentation, as variants like 0819R-54H may exist with different tolerances. Confirm RoHS compliance status, as some listings indicate non-compliance. Ensure the required packaging format matches availability, typically supplied in reels for automated assembly processes.

Selection Notes

Select this component when an 18 µH inductance value is required for RF environments. Consider the 3% tolerance and 112 mA current rating against circuit demands. Verify that the unshielded design does not interfere with nearby sensitive components due to potential magnetic field emission.

Part Context

This part belongs to the Delevan 0819 series of fixed inductors. The series offers various inductance values tailored for RF and general-purpose applications. These components are characterized by their molded construction and axial leads, providing a compact solution for through-hole integration in electronic assemblies.

Replacement Considerations

The 0819R-54H is a related variant within the same product family. Users should verify if the specific tolerance or packaging differences between these identifiers impact the design requirements before substitution.
