108-393FS

Overview

The Delevan 108-393FS is a fixed inductor with an inductance of 39 µH and a tolerance of ±1%. It features a maximum DC current rating of 38 mA and a maximum DC resistance (DCR) of 17 Ohms. The component utilizes an iron core and is unshielded. It operates within a temperature range of -55°C to +125°C. The package is a non-standard, two-lead axial form factor.

Feature Summary

• Unshielded construction for applications requiring minimal magnetic interference
• Iron core material providing stable inductance characteristics
• Axial leaded package design suitable for through-hole mounting

Applications

• RF choke circuits
• Filtering applications in electronic systems
• Signal processing components

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official API Delevan documentation to ensure correct component selection. Confirm that the unshielded axial package meets the mechanical constraints of the target PCB layout. Check compliance requirements such as RoHS status if applicable to the end product specifications.

Selection Notes

Select this component when a 39 µH inductance value is required with a low current handling capacity of 38 mA. The high DC resistance of 17 Ohms must be accounted for in circuit design. Ensure the unshielded nature does not interfere with nearby sensitive components or traces.

Part Context

This part belongs to the Delevan fixed inductor series, designed for general electronic use. It represents a standard axial leaded option within the manufacturer's portfolio, distinct from their surface mount RF inductor lines. The component is intended for reliable performance in various frequency ranges.

Replacement Considerations

Direct substitutes may include other Delevan axial inductors with matching electrical parameters. Verify cross-reference data sheets for equivalent inductance, current ratings, and physical dimensions before substitution.
