108R-123JS

Overview

The Delevan 108R-123JS is a fixed surface-mount power inductor with an inductance of 12 µH and a tolerance of ±5%. It features a maximum DC resistance of 4 Ohms and a rated current of 79 mA. The component utilizes a nonstandard package footprint with two leads, designed for direct PCB mounting.

Feature Summary

• Fixed inductance value suitable for stable circuit filtering
• Surface mount construction for automated assembly
• Two-lead terminal configuration for standard mounting

Applications

• Power supply input filtering
• DC-DC converter circuits
• General electronic signal conditioning

Procurement Notes

Verify the specific manufacturer part number against official API Delevan documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with existing PCB footprints due to the nonstandard package design. Cross-reference datasheets for thermal performance limits and saturation characteristics before final integration.

Selection Notes

Select this component when a 12 µH inductance with low current handling is required for power applications. Consider the high DC resistance relative to other power inductors as it impacts efficiency. Evaluate the nonstandard footprint requirements against available board space and manufacturing capabilities.

Part Context

This component belongs to the Delevan fixed inductor family, specifically designed for surface-mount technology. It serves as a passive energy storage element within electronic circuits, providing impedance to AC signals while allowing DC current to pass.

Replacement Considerations

Direct substitutes include the 108R-123J variant from the same manufacturer series. Verify pinout compatibility and mechanical height constraints when evaluating alternative suppliers or updated component revisions.
