108R-393K

Overview

The Delevan 108R-393K is a fixed surface-mount inductor with a nominal inductance of 39 µH and a tolerance of ±10%. It features an unshielded nonstandard two-lead package design. The component has a maximum DC resistance of 17 Ohms and a rated current of 38 mA. It utilizes a ferrite core material and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded construction for applications requiring minimal magnetic interference
• Nonstandard two-lead surface-mount package configuration
• Ferrite core material providing stable inductance characteristics

Applications

• RF choke circuits
• Signal filtering applications
• General-purpose electronic circuitry

Procurement Notes

Verify the specific manufacturer designation, as API Delevan components may be listed under API or Delevan branding. Confirm the exact package dimensions against the official datasheet due to the nonstandard footprint. Ensure the unshielded nature aligns with your PCB layout requirements to prevent unintended coupling.

Selection Notes

Select this component when a 39 µH inductance value is required in a compact surface-mount form factor. Consider the 17 Ohm DC resistance and 38 mA current rating to ensure compatibility with your circuit's power budget. The unshielded design necessitates careful placement relative to sensitive signal traces.

Part Context

This part belongs to the Delevan fixed inductor family, characterized by small surface-mount footprints. It serves as a passive component for energy storage and filtering in low-power electronic systems, distinct from shielded or through-hole variants in the same series.

Replacement Considerations

Direct substitutes include other 39 µH SMD inductors with similar current ratings and resistance values. Verify pin compatibility and thermal performance before substitution.
