108-223GS

Overview

The Delevan 108-223GS is a fixed surface-mount RF inductor designed for high-frequency applications. It features an inductance of 22 µH with a tight tolerance of 2%. The component exhibits a maximum DC resistance of 7.5 Ohms and supports a maximum DC current of 57 mA. Constructed as an unshielded chip SMT device, it utilizes a nonstandard two-lead package configuration suitable for PCB mounting.

Feature Summary

• Unshielded construction for specific RF layout requirements
• High precision 2% inductance tolerance
• Surface-mount technology (SMT) implementation

Applications

• RF choke circuits
• High-frequency signal filtering
• Impedance matching networks

Procurement Notes

Verify the exact physical dimensions and lead configuration against the official datasheet, as the package is classified as nonstandard. Confirm RoHS compliance status and manufacturer specifications prior to integration. Ensure the selected variant matches the required 22 µH value and 57 mA current rating for the target application.

Selection Notes

Select this component when precise inductance control is critical due to its 2% tolerance. The unshielded design requires careful PCB layout to manage electromagnetic interference. Verify that the 57 mA current limit and 7.5 Ohm resistance align with the circuit's power and signal integrity requirements.

Part Context

This part belongs to the Delevan family of fixed RF inductors. It shares the 22 µH nominal value with other series members but differs significantly in shielding, tolerance, and package style. The 108 prefix typically denotes a specific form factor within the manufacturer's broader portfolio of passive components.

Replacement Considerations

Direct substitutes include parts with identical 22 µH inductance, 2% tolerance, and similar current ratings. Verify pin compatibility and thermal characteristics before swapping. Cross-reference with API Delevan documentation for approved alternative part numbers.
