108R-123GS

Overview

The Delevan 108R-123GS is a fixed surface-mount RF inductor with an inductance of 12 µH and a tolerance of ±2%. It features a maximum DC resistance of 4 Ohms and a current rating of 79 mA. The component utilizes an iron core and measures 2.54 mm in length, 2.54 mm in width, and 1.91 mm in height. It employs standard SMD/SMT termination for PCB mounting.

Feature Summary

• Surface-mount design for automated PCB assembly
• High precision ±2% inductance tolerance
• Iron core construction for stable performance

Applications

• RF circuit filtering
• Impedance matching networks
• Signal processing components

Procurement Notes

Verify the specific manufacturer lifecycle status before integration, as availability may be restricted. Confirm that the ±2% tolerance and 4 Ohm DC resistance meet strict circuit requirements. Ensure the non-standard lead configuration aligns with the target PCB footprint design to prevent assembly errors.

Selection Notes

Select this component when high precision is required for RF applications. The small 1008 metric package size suits space-constrained designs. Verify compatibility with peak reflow temperatures and ensure the 79 mA current rating exceeds the expected operational load to maintain inductance stability.
