108-473FS

Overview

The Delevan 108-473FS is a fixed leaded inductor with an inductance of 47 µH and a tolerance of ±5%. It features a maximum DC resistance of 19 Ohms and a rated current of 36 mA. The component has non-standard dimensions of 2.54 mm x 2.54 mm x 1.91 mm.

Feature Summary

• Fixed inductance value for stable circuit performance
• Leaded axial termination style for through-hole mounting
• Compact physical footprint suitable for space-constrained designs

Applications

• RF circuits requiring specific inductance values
• General purpose filtering applications
• Signal processing stages

Procurement Notes

Verify the current lifecycle status as sources indicate obsolete or limited availability. Confirm RoHS compliance requirements against project specifications, as documentation suggests non-compliance. Ensure the 36 mA current rating meets design needs before ordering.

Selection Notes

Select this component when a 47 µH inductance with high DC resistance is required. The 36 mA current limit dictates suitability for low-power signal paths rather than power delivery. Verify mechanical fit within the 2.54 mm square footprint constraint.

Part Context

This part belongs to the API Delevan fixed inductor family. It utilizes a molded construction typical of legacy RF components. The manufacturer specializes in passive components for telecommunications and industrial electronics.

Replacement Considerations

Check for direct substitutes from API Delevan's active inventory. Evaluate generic leaded inductors with matching 47 µH, 36 mA, and 19 Ohm parameters if original stock is unavailable.
