105-121G

Overview

The Delevan 105-121G is a fixed surface-mount RF inductor with an inductance of 120 nH. It features a non-shielded construction and a maximum DC resistance of 140 mOhms. The component supports a maximum current rating of 830 mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

Unshielded SMD design for minimal parasitic capacitance
High-current capability suitable for RF power stages
Standard two-terminal surface mount configuration

Applications

RF matching networks
Impedance transformation circuits
Filter components in radio frequency systems

Procurement Notes

Verify the specific suffix and manufacturer documentation to confirm exact electrical tolerances and RoHS compliance status, as legacy Delevan parts may vary. Confirm package dimensions against PCB footprint requirements before integration.

Selection Notes

Select this unshielded variant when magnetic field isolation is not required and lower parasitic capacitance is critical. Ensure the operating current remains below the 830 mA limit to prevent saturation or thermal issues.

Part Context

This component belongs to the Delevan fixed inductor family designed for high-frequency applications. It utilizes a wire-wound construction on a ceramic core, providing stable performance across wide temperature ranges typical of RF circuitry.

Replacement Considerations

The 105R-121G is a related variant from the same manufacturer series. Verify pin compatibility and tolerance specifications when considering substitution.
