108-393GS

Overview

The Delevan 108-393GS is a fixed surface-mount power inductor with an inductance of 39 µH and a tolerance of ±2%. It features a maximum DC resistance of 17 Ohms and a rated current of 38 mA. The component measures 2.54 mm by 2.54 mm with a height of 1.91 mm. It operates within a temperature range of -55°C to 125°C.

Feature Summary

• Unshielded wirewound construction for RF applications
• High Q factor at 2.5 MHz
• Nonstandard two-lead SMD package

Applications

• RF circuits
• Power filtering
• Signal processing

Procurement Notes

Verify the specific ordering suffix, as variants like 108R-393GS may differ in RoHS compliance or packaging. Confirm that the standard bulk packaging aligns with assembly requirements. Ensure the unshielded design does not conflict with EMI constraints in the target application environment.

Selection Notes

Select this component when a precise 39 µH value with tight 2% tolerance is required for non-standard footprint layouts. Consider the high DC resistance and low current rating for suitability in low-power signal paths rather than high-current power delivery networks.

Part Context

This part belongs to the 108 series of fixed inductors from API Delevan. It shares the 39 µH electrical specification with other members of the family but utilizes a distinct nonstandard two-lead surface mount package configuration.

Replacement Considerations

Direct substitutes include the 108R-393GS variant from the same manufacturer.
