Overview
The Delevan 108R-393GS is a fixed surface-mount power inductor with an inductance of 39 µH and a tolerance of ±5%. It features a non-shielded design with a maximum DC resistance of 17 Ohms and a rated current of 38 mA. The component utilizes a ceramic core and operates within a temperature range of -55°C to +125°C. Its physical dimensions are approximately 2.54 mm in length, 2.54 mm in width, and 1.65 mm in height, housed in a standard SMD package.
Feature Summary
- Non-shielded construction for minimal magnetic interference
- Ceramic core material for stable performance
- Surface-mount technology (SMD) compatibility
- High-temperature operational capability
Applications
- RF circuit filtering
- Signal processing applications
- General-purpose electronic circuits
Procurement Notes
Verify the specific suffix designation against official API Delevan documentation to confirm exact tolerance and electrical characteristics. Ensure that the non-shielded configuration aligns with the electromagnetic interference requirements of the target application. Cross-reference the manufacturer's latest datasheet to validate current ratings and thermal limits before integration.
Selection Notes
Select this component when a non-shielded inductor is required to prevent magnetic coupling issues in sensitive RF layouts. Consider the relatively high DC resistance and low current rating for suitability in signal-level rather than high-power applications. Evaluate the physical footprint constraints against the specified 2.54 x 2.54 mm dimensions.
Part Context
This part belongs to the 108 series of fixed inductors from API Delevan, designed for surface-mount assembly. The series offers various inductance values tailored for RF and general electronic applications. The 108R-393GS specifically addresses needs for precise inductance in compact, non-shielded environments.
Replacement Considerations
Direct substitutes include other 39 µH SMD inductors with similar current ratings and non-shielded designs. Verify mechanical footprint compatibility and electrical parameters such as DCR and Q-factor when considering alternative manufacturers or series.
