106-121J

Overview

The Delevan 106-121J is an unshielded surface-mount RF inductor with a nominal inductance of 120 nH and a tolerance of 1%. It features a maximum DC resistance of 200 mOhms and supports a maximum DC current of 710 mA. The component has a minimum Q factor of 42 at 25 MHz and a self-resonant frequency of 400 MHz. Its physical dimensions are 3.94 mm in length, 2.79 mm in width, and 1.91 mm in height. The device utilizes standard SMD/SMT termination and is packaged in bulk quantities.

Feature Summary

• Unshielded construction for minimal magnetic interference
• High precision 1% inductance tolerance
• Surface-mount design for PCB integration

Applications

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

Procurement Notes

Verify the specific suffix 'J' against official manufacturer documentation to confirm the exact 1% tolerance specification. Confirm RoHS compliance status as sources vary. Check for End-of-Life notifications or discontinuance notices from API Delevan prior to procurement planning.

Selection Notes

Select this component when precise inductance control is required for RF applications. Ensure the unshielded nature aligns with the electromagnetic compatibility requirements of the target circuit. Verify that the 710 mA current rating meets the operational demands of the application.

Part Context

This part belongs to the Delevan 106 series of RF inductors. It shares the same form factor and electrical characteristics as the 106-121F model, differing primarily in the tolerance designation indicated by the suffix.

Replacement Considerations

The 106-121F is a confirmed substitute with identical specifications except for tolerance.
