106-271F

Overview

The Delevan 106-271F is a fixed surface-mount RF inductor with a nominal inductance of 270 nH and a tolerance of ±1%. It features an unshielded wirewound construction on an iron core, resulting in a maximum DC resistance of 370 mΩ. The component supports a maximum DC current of 520 mA and offers a minimum Q factor of 42 at its self-resonant frequency of 400 MHz. Designed for PCB mounting, it operates within a temperature range of -55 °C to +125 °C.

Feature Summary

• Precision inductance control with ±1% tolerance
• Unshielded wirewound design for high-Q performance
• Robust thermal stability across extended operating temperatures

Applications

• RF signal filtering circuits
• Impedance matching networks
• High-frequency tuning applications

Procurement Notes

Verify the specific ordering suffix and lead time requirements directly with API Delevan or authorized distributors. Confirm RoHS compliance status as historical data indicates variations within this series. Ensure the unshielded package style aligns with your layout constraints to prevent parasitic coupling issues during integration.

Selection Notes

Select this component when precise inductance values are critical for RF circuitry. The unshielded construction requires careful placement to minimize electromagnetic interference with adjacent traces. Evaluate the 520 mA current rating against peak load conditions to ensure reliable operation without saturation.

Part Context

This part belongs to the Delevan 106 series of general-purpose RF inductors. It shares the same physical footprint and electrical architecture as other variants in the line, differing primarily in inductance value and tolerance specifications. The series is characterized by wirewound technology suitable for stable RF performance.

Replacement Considerations

Direct substitutes include the 106-121F for lower inductance needs or the 4302-271F for shielded alternatives. Verify that replacement parts match the 270 nH target and maintain similar Q-factor characteristics for equivalent circuit behavior.
