• Low-current signal processing

Procurement Notes

Verify component status as the 108-473KS is listed as obsolete by major distributors. Confirm availability through secondary markets or authorized stockists if immediate procurement is required. Ensure compatibility with existing PCB footprints before sourcing replacement units.

Selection Notes

Select this component for non-shielded SMD applications requiring 47 µH inductance at low current levels. Consider thermal performance limits up to 125°C during operation. Evaluate alternative available parts if obsolescence impacts supply chain stability.

Part Context

This part belongs to the API Delevan fixed inductor family designed for RF and general electronic applications. It utilizes standard surface-mount technology for integration into printed circuit boards. The manufacturer specializes in passive components for telecommunications and industrial electronics.

Replacement Considerations

Public confirmed substitute part numbers are not available due to the obsolete status of the 108-473KS. Engineers should evaluate equivalent inductance values from current production lines that match the 47 µH specification and similar physical dimensions.
