Procurement Notes

Verify component status as obsolete or limited availability through authorized distributors. Confirm RoHS compliance details directly with the manufacturer API Delevan. Ensure the specific suffix GS matches design requirements for tolerance and shielding before procurement. Cross-reference datasheet revisions for any parameter updates.

Selection Notes

Select this component for applications requiring high-inductance RF chokes with tight tolerance. Compare against non-shielded alternatives if EMI sensitivity is low. Verify footprint compatibility with existing PCB layouts. Consider thermal management given the 25 Ohm DC resistance at higher current loads.

Part Context

This part belongs to the Delevan 108R series of surface-mount RF inductors. These components are engineered for high-frequency applications where signal integrity is critical. The series offers various inductance values with shielded options to prevent crosstalk in dense circuit boards.

Replacement Considerations

Public confirmed substitute: 108R-683J (±5% tolerance). Verify functional equivalence regarding shielding and Q-factor before substitution.
