103R-222GS

Overview

The Delevan 103R-222GS is an unshielded surface-mount RF inductor with a nominal inductance of 2.2 µH and a tolerance of ±2%. It features a maximum DC resistance of 1 Ohm and a rated current of 310 mA. The component utilizes a nonstandard two-lead package design suitable for PCB mounting.

Feature Summary

• Unshielded construction for specific RF circuit requirements
• High precision ±2% inductance tolerance
• Nonstandard two-lead SMD package configuration

Applications

• RF signal processing circuits
• Impedance matching networks
• Filter applications in communication equipment

Procurement Notes

Verify the exact physical dimensions against the official datasheet due to the nonstandard package designation. Confirm RoHS compliance status as documentation may vary by production batch. Ensure the supplier provides the manufacturer datasheet for accurate footprint verification before integration.

Selection Notes

Select this component when high inductance accuracy is required alongside a compact, nonstandard form factor. The unshielded design suits applications where magnetic interference coupling is managed externally. Verify that the 310 mA current rating meets the operational load requirements.

Part Context

This part belongs to the Delevan fixed inductor portfolio, specifically designed for radio frequency applications. It represents a specialized variant within the broader SMD inductor category, distinguished by its unique lead configuration and tight tolerance specifications compared to standard chip inductors.

Replacement Considerations

Direct substitutes must match the 2.2 µH value, ±2% tolerance, and 1 Ohm DCR. Due to the nonstandard package, mechanical compatibility requires careful evaluation of alternative manufacturers' footprint data.
