108R-473J

Overview

The Delevan 108R-473J is a fixed surface-mount inductor from the 105(R) and 108(R) series. It features an unshielded ferrite core design with a nominal inductance of 47 µH and a tolerance of ±5%. The component supports a maximum DC current of 36 mA and has a maximum DC resistance of 19 Ohms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Unshielded construction for specific RF applications
• Ferrite core material for stable inductance
• Surface-mount package for automated assembly

Applications

• RF circuit filtering
• General-purpose signal processing
• High-frequency impedance matching

Procurement Notes

Verify the manufacturer designation, as API Delevan Inc. is also listed for this part number. Confirm the exact physical dimensions against the datasheet, as the package is described as non-standard. Ensure the 36 mA current rating meets the specific circuit requirements before integration.

Selection Notes

Select this component when an unshielded inductor is required to minimize magnetic interference with nearby traces. The high DC resistance and low current rating make it suitable for low-power signal paths rather than power delivery lines. Verify compatibility with standard reflow soldering profiles.

Part Context

This part belongs to the 108(R) series of fixed inductors manufactured by Delevan. These components are designed for surface-mount technology (SMT) applications. The series utilizes ferrite cores to achieve specific inductance values in compact footprints suitable for dense PCB layouts.

Replacement Considerations

Cross-reference with other 47 µH SMD inductors having similar current ratings. Verify that substitute parts maintain the unshielded characteristic if magnetic coupling is critical.
