108-123KS

Overview

The Delevan 108-123KS is a fixed surface-mount power inductor with a nominal inductance of 12 µH. It features a shielded construction and a maximum DC resistance of 4 Ohms. The component supports a maximum DC current of 79 mA and operates within a temperature range of -55 °C to +125 °C. It utilizes a ferrite core and is housed in a 108 (2520 metric) package footprint.

Feature Summary

• Shielded surface-mount design for electromagnetic interference reduction
• Ferrite core construction for stable inductance characteristics
• High-temperature operation capability up to 125 °C

Applications

• RF circuit filtering
• Power supply input/output stages
• General-purpose signal conditioning

Procurement Notes

Verify compliance status as the component contains lead and is RoHS non-compliant. Confirm availability as the part may be obsolete or discontinued by the manufacturer. Ensure substitute components are evaluated for equivalent electrical parameters and physical dimensions before integration into new designs.

Selection Notes

Select this component for applications requiring a compact, shielded inductor with moderate current handling capabilities. Consider the 4 Ohm DC resistance and 79 mA current limit when designing power paths. Verify that the operating environment remains within the specified -55 °C to +125 °C range for reliable performance.

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 in electronic circuits, providing impedance control and noise suppression in RF and power management applications.

Replacement Considerations

The 108R-123KS is listed as an obsolete product. Evaluate available substitutes from the same manufacturer series or compatible third-party equivalents that match the 12 µH inductance, 108 package size, and shielding requirements.
