108-393HS

Overview

The Delevan 108-393HS is a fixed surface-mount RF inductor with an inductance of 39 µH and a tolerance of ±10%. It features a maximum DC resistance of 17 Ohms and a rated current of 38 mA. The component utilizes a ferrite core and is housed in a nonstandard SMD package. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Shielded or unshielded construction options available within the series
• Ferrite core material for stable RF performance
• Surface-mount design for automated PCB assembly

Applications

• RF choke circuits
• Impedance matching networks
• Filtering applications in radio frequency systems

Procurement Notes

Verify the specific suffix (e.g., HS, JS) against the datasheet to confirm shielding status and exact electrical parameters, as variations exist within the 108R series. Confirm RoHS compliance status for the specific revision. Ensure the nonstandard footprint dimensions are compatible with the target PCB layout before finalizing procurement.

Selection Notes

Select this component for applications requiring a 39 µH value in a compact surface-mount form factor. Compare the 17 Ohm DCR and 38 mA rating against circuit requirements. Consider the 108R-393JS variant if shielded performance is required instead of the unshielded 108-393HS configuration.

Part Context

This part belongs to the Delevan 108/108R series of fixed RF inductors. These components are designed for high-frequency applications where small size and consistent inductance are critical. The series offers various values and mounting styles to support diverse RF circuit designs.

Replacement Considerations

The 108R-393JS is a direct substitute within the same series, offering similar electrical characteristics but potentially different shielding properties. Verify pinout and footprint compatibility before substitution.
