108-473H

Overview

The Delevan 108-473H is a fixed surface-mount inductor with an inductance of 47 µH and a tolerance of ±3%. It features a maximum DC resistance of 19 Ohms and a rated current of 36 mA. The component utilizes a wirewound construction and is unshielded, belonging to the 108 series designed for RF applications.

Feature Summary

• Wirewound construction for stable inductance
• Unshielded design suitable for specific RF layouts
• Surface-mount package for automated assembly

Applications

• RF circuit filtering
• Signal processing networks
• Impedance matching stages

Procurement Notes

Verify component authenticity through authorized API Delevan channels or certified distributors. Request original datasheets and material certificates to confirm RoHS compliance and manufacturing origin. Ensure storage conditions meet moisture sensitivity level requirements prior to reflow soldering processes.

Selection Notes

Select this part for RF designs requiring precise 47 µH inductance with tight tolerance. Consider the 19 Ohm DC resistance impact on signal loss. Evaluate the unshielded nature against nearby magnetic components to prevent interference in dense PCB layouts.

Part Context

Part of the Delevan 108 series, this component targets radio frequency environments. It offers a compact surface-mount footprint compared to axial leads. The unshielded variant provides flexibility for custom magnetic field management in specialized RF hardware.

Replacement Considerations

Direct substitutes include the 108R-473H from the same manufacturer family. Verify equivalent electrical parameters such as current rating and self-resonant frequency before cross-referencing with other brands.
