103R-223G

Overview

The Delevan 103R-223G is a fixed surface-mount RF inductor with a nominal inductance of 22 µH and a tolerance of ±2%. It features a maximum DC resistance of 6.4 Ω and a rated current of 125 mA. The component utilizes a ferrite core and wirewound construction within a rectangular chip package measuring 2.54 mm in length, 1.27 mm in width, and 1.91 mm in height. Designed for operation between -55 °C and +125 °C, it employs two standard SMD terminals.

Feature Summary

• Wirewound ferrite core construction for stable RF performance
• Rectangular surface-mount footprint for automated PCB assembly
• Wide operating temperature range suitable for harsh environments

Applications

• RF signal filtering circuits
• General purpose inductive applications
• Power supply choke implementations

Procurement Notes

Verify the specific ordering suffix to confirm compliance status and terminal finish. The 'G' suffix typically indicates lead-free composition, whereas other variants may contain lead. Confirm RoHS directive alignment against project requirements before finalizing procurement orders to ensure regulatory adherence.

Selection Notes

Select this component when a high-inductance value is required in a compact SMD form factor. Evaluate the 125 mA current rating against peak load conditions to prevent saturation. Consider the 6.4 Ω DC resistance impact on voltage drop and power dissipation within the target circuit topology.

Part Context

This part belongs to the 103R series of fixed inductors manufactured by API Delevan. The series offers various inductance values tailored for RF and general-purpose applications. The 103R-223G specifically addresses needs for higher inductance in space-constrained designs compared to lower-value counterparts.

Replacement Considerations

Direct substitutes include the PD43R-223M from the same manufacturer family, which shares similar electrical characteristics but differs in physical dimensions and packaging specifications.
