106-391G

Overview

The Delevan 106-391G is a fixed surface-mount RF inductor with an inductance of 390 nH and a tolerance of ±1%. It features a maximum DC current rating of 475 mA and a maximum DC resistance of 450 mOhms. The component utilizes a non-standard two-lead package design, distinguishing it from standard SMD footprints. It operates within a temperature range of -55°C to +125°C and exhibits a minimum Q factor of 30 at its self-resonant frequency.

Feature Summary

• Non-standard two-lead surface mount construction for specialized PCB layouts
• Temperature stable performance across a wide operating range
• High Q factor suitable for RF choke applications

Applications

• RF signal filtering
• RF choke circuits
• Impedance matching networks

Procurement Notes

Verify the specific lead configuration against the target PCB footprint, as this component uses a non-standard two-lead package rather than a conventional SMD land pattern. Confirm that the 475 mA current rating meets the circuit requirements. Ensure compatibility with the specified temperature range for the intended environment.

Selection Notes

Select this part when a non-standard two-lead form factor is required for RF inductance. Compare the 450 mOhm DC resistance against circuit loss requirements. Evaluate the 390 nH value against the target frequency band to ensure proper impedance characteristics and self-resonant behavior.

Part Context

This component belongs to the Delevan 106 series of fixed RF inductors. It shares the 390 nH nominal value with other variants like the 106-391F but differs in packaging style. The series is designed for high-frequency applications requiring stable inductance values.

Replacement Considerations

The 106-391F is a similar inductance variant but typically utilizes a standard SMD package. Verify mechanical fit and lead configuration before substitution.
