106-121G

Overview

The Delevan 106-121G is an unshielded surface-mount RF inductor with a nominal inductance of 120 nH and a tolerance of ±5%. 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.

Feature Summary

• Unshielded wirewound construction for RF applications
• High self-resonant frequency capability
• Compact surface-mount form factor

Applications

• RF circuit filtering
• Impedance matching networks
• General RF signal processing

Procurement Notes

Verify the specific suffix (G vs F) as it may indicate variations in tolerance or packaging. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as records vary. Check for end-of-life notifications or discontinuance notices prior to finalizing procurement plans.

Selection Notes

Select this component for high-frequency RF designs requiring low parasitic capacitance due to its unshielded design. Ensure the operating current remains below the 710 mA limit to prevent saturation. Verify that the 120 nH value aligns with the target resonant frequency requirements of the application.

Part Context

This part belongs to the Delevan 106 series of fixed RF inductors. It is functionally similar to the 106-121F but typically differs in tolerance specifications. The series is designed for general-purpose RF applications where shielding is not required.

Replacement Considerations

The 106-121F is a documented alternative within the same series. Verify if the tolerance difference meets the design requirements before substitution.
