High-frequency filtering

Procurement Notes

This component is officially discontinued and no longer manufactured by the producer. Verification of availability requires checking authorized distributors for remaining stock or surplus inventory. Procurement should focus on identifying verified sources for obsolete parts rather than new production orders.

Selection Notes

Engineers replacing this part must account for its discontinuation status. Selection criteria should prioritize matching the 100 uH inductance, 31 Ohm DC resistance, and 2.54 x 2.54 mm footprint. Compatibility with existing RF circuit designs is essential when sourcing substitutes.

Part Context

The 108-104KS belongs to the 108R series of fixed RF inductors produced by API Delevan Inc. This series is characterized by small surface-mount packages suitable for high-frequency applications. The specific model represents a legacy component within the broader category of passive electronic components.
