105R-121GS

Overview

The Delevan 105R-121GS is a surface-mount RF inductor designed for high-frequency applications. It features an iron core and offers an inductance of 120 nH with a tolerance of ±10%. The component supports a maximum DC current of 830 mA and exhibits a maximum DC resistance of 140 mOhms. Operating within a temperature range of -55°C to +125°C, it utilizes a tape and reel package for automated assembly.

Feature Summary

• Utilizes an iron core for stable RF performance
• Designed for surface-mount PCB integration
• Supports wide operating temperature ranges

Applications

• RF circuit filtering
• High-frequency signal processing
• Power line chokes in RF environments

Procurement Notes

Verify the specific suffix 'GS' against official API Delevan documentation to confirm lead-free status and RoHS compliance details. Ensure the ordering quantity aligns with the manufacturer's standard tape and reel packaging requirements. Cross-reference the part number with current distributor availability to confirm stock status and delivery timelines prior to finalizing procurement orders.

Selection Notes

Select this component when a compact SMD inductor with 120 nH nominal value is required for RF circuits. Consider the 830 mA current rating and 140 mOhms resistance for power loss calculations. Verify that the iron core material meets the specific frequency response needs of the application design.

Part Context

This component belongs to the API Delevan fixed inductor portfolio, specifically categorized under RF inductors. It shares the 120 nH inductance value with other variants in the series but differs in package style and termination type compared to through-hole or shielded alternatives.

Replacement Considerations

Direct substitutes include the 105R-121G and 105R-121KS, which share identical electrical specifications such as 120 nH inductance and 830 mA current rating. Verify package compatibility and termination finish before substitution.
