105-391F

Overview

The Delevan 105-391F is a fixed surface-mount RF inductor with an inductance of 390 nH. It features an unshielded iron core design and a nonstandard two-lead termination style. The component supports a maximum DC current of 585 mA and has a maximum DC resistance of 280 mOhms. It is designed for PCB mounting and operates within the RF spectrum.

Feature Summary

• Unshielded construction utilizing an iron core material
• Nonstandard two-lead termination configuration
• Surface-mount technology (SMT) installation

Applications

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

Procurement Notes

Verify the specific lead configuration against schematic requirements, as this component utilizes a nonstandard two-lead termination rather than standard SMD pads. Confirm that the unshielded design aligns with electromagnetic interference constraints for the target application environment before finalizing procurement.

Selection Notes

Select this part when a compact, unshielded RF choke is required with moderate current handling capabilities. The nonstandard lead style necessitates careful footprint design. Ensure the operating frequency remains below the self-resonant limit to maintain inductive behavior.

Part Context

This component belongs to the Delevan 105 series of fixed RF inductors. It shares the same nominal inductance value as other variants like the 105-391J but differs in tolerance, shielding status, and physical termination style. The series is characterized by iron core construction for stable RF performance.

Replacement Considerations

The 105-391J is a related variant with identical inductance but different tolerance and shielding. Verify mechanical compatibility due to potential differences in lead style or package dimensions before substitution.
