106-123H

Overview

The Delevan 106-123H is a fixed surface-mount inductor with a nominal inductance of 12 µH. It features an unshielded wirewound construction using an iron core, housed in a nonstandard two-terminal package. The component has a maximum DC resistance of 4 Ohms and supports a maximum DC current of 150 mA. Electrical characteristics include a minimum Q factor of 32 at 2.5 MHz and a self-resonant frequency of 26 MHz.

Feature Summary

• Wirewound construction with an iron core for stable inductance performance
• Unshielded design suitable for applications where magnetic shielding is not required
• Two-terminal surface mount configuration for standard PCB integration

Applications

• RF circuit filtering
• General purpose signal processing
• Power supply choke applications

Procurement Notes

Verify RoHS compliance status as the component may contain lead. Confirm that the nonstandard package dimensions match the target PCB footprint. Ensure the 150 mA current rating meets the operational requirements of the specific circuit application to prevent saturation or overheating.

Selection Notes

Select this component when a 12 µH inductance value is required with a 4 Ohm DC resistance limit. The unshielded design necessitates careful layout planning to minimize electromagnetic interference with nearby traces. Verify that the operating temperature range covers the intended environmental conditions.

Part Context

This part belongs to the API Delevan fixed inductor family, which offers various inductance values and tolerance options. The 106 series typically utilizes wirewound technology on iron cores, distinguishing it from ferrite-based power inductors in the same manufacturer's portfolio.

Replacement Considerations

The 106-123G is a documented variant within the same series. Both share identical electrical parameters including 12 µH inductance, 4 Ohm DCR, and 150 mA current rating. Verify package compatibility before substitution.
