0805RB-471XMRC

Overview

The Coilcraft 0805RB-471XMRC is a single-line surface-mount ferrite bead designed for high-speed signal integrity. It features an impedance of 470 Ohms at the standard test frequency, with a maximum DC resistance of 295 milliohms and a rated current handling capacity of 800 mA. The component utilizes a ferrite core within a compact 0805 (2012 metric) package, measuring 2.03 mm in length, 1.27 mm in width, and 0.93 mm in height. It operates reliably across a temperature range from -40°C to +125°C and complies with RoHS standards.

Feature Summary

• Provides effective electromagnetic interference suppression for single data lines through high impedance characteristics.
• Supports high-speed digital signals while maintaining low insertion loss via minimal DC resistance.
• Constructed with a robust ferrite core suitable for demanding thermal environments.

Applications

• High-speed USB interface protection
• HDMI signal line filtering
• General-purpose EMI suppression on single-ended traces

Procurement Notes

Verify the specific suffix XMRC against the manufacturer's latest datasheet to confirm packaging type and compliance status. Ensure the ordering part number matches the required impedance tolerance and current rating specifications for your circuit design before finalizing procurement.

Selection Notes

Select this component when a single-line ferrite bead is required for high-speed interfaces. Evaluate the 470 Ohm impedance profile against the noise spectrum of the target application. Confirm that the 800 mA current rating exceeds the peak operating current of the protected line to prevent saturation or excessive heating.

Part Context

This component belongs to the 0805RB series of wirewound ferrite beads manufactured by Coilcraft. These parts are engineered for surface-mount technology applications requiring compact footprints. The series offers various impedance values tailored for different frequency ranges and signal integrity requirements in modern electronic assemblies.

Replacement Considerations

Consult official Coilcraft documentation for verified cross-reference part numbers. Do not substitute based solely on package dimensions; verify impedance curves and current ratings match the original design intent.
