0805USBF-672MRC

Overview

The Coilcraft 0805USBF-672MRC is a single-channel common mode filter choke designed for high-speed signal lines. It features an inductance of 434 nH and a maximum DC resistance of 0.37 ohms. The component supports a maximum DC current of 450 mA and operates within a temperature range of -40°C to +125°C. Housed in a compact 0805 surface-mount package, it utilizes ferrite core material to provide effective electromagnetic interference suppression.

Feature Summary

• Engineered specifically for filtering high-speed digital signals
• Utilizes ferrite core technology for effective noise attenuation
• Compact surface-mount footprint suitable for dense PCB layouts

Applications

• High-speed USB data line protection
• Signal integrity enhancement in digital communication interfaces
• Electromagnetic interference suppression in portable electronics

Procurement Notes

Verify the specific suffix MRC against official Coilcraft documentation to confirm tape-and-reel packaging configuration. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as regulatory markings may vary by production batch. Ensure the component meets all environmental operating specifications required for the target application before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring low-profile common mode filtering for high-speed data transmission. Evaluate the 434 nH inductance value against the specific frequency spectrum of the noise to be suppressed. Ensure the 450 mA current rating exceeds the maximum operational current of the protected signal line to prevent saturation and maintain performance stability under load conditions.

Part Context

This component belongs to the 0805USBF series from Coilcraft, which specializes in common mode chokes optimized for high-speed signal applications. The series offers various inductance values within the standard 0805 package size, allowing designers to balance space constraints with filtering requirements. These components are integral to maintaining signal integrity in modern electronic devices where electromagnetic compatibility is critical.

Replacement Considerations

Consult official Coilcraft documentation for verified substitute part numbers within the same series or equivalent specifications. Do not assume interchangeability based solely on package dimensions; verify electrical parameters such as inductance, DC resistance, and current ratings match the original design requirements.
