EMI8041BMUTAG

Common Mode Chokes Overview

The EMI8041BMUTAG is a single-pair common mode filter circuit designed for high-speed data interfaces. It provides electromagnetic interference (EMI) filtering and electrostatic discharge (ESD) protection in a compact surface-mount package. The device features a common mode choke with integrated TVS diodes, offering attenuation greater than 750 MHz for HDMI applications. Key electrical characteristics include a typical DC resistance of 6 Ohms and a rated current of 100 mA. The component operates within a temperature range of -40°C to +85°C and utilizes a 6-UFDFN package.

Common Mode Chokes Feature Summary

• Integrated EMI filtering and ESD protection in a single compact package
• Designed for high-speed data lines with superior attenuation above 750 MHz
• Suitable for HDMI interface applications requiring signal integrity maintenance

Common Mode Chokes Applications

• HDMI interface protection
• High-speed data line filtering
• Consumer electronics signal conditioning

Common Mode Chokes Procurement Notes

Verify the specific suffix 'B' against the manufacturer's latest documentation, as it may indicate a specific binning or revision level not present in the base part number. Confirm the package type matches the design footprint requirements. Ensure compliance with RoHS directives if required by the end application. Cross-reference the Mouser and DigiKey listings for accurate datasheet versions before finalizing procurement specifications.

Common Mode Chokes Selection Notes

Select this component when space constraints require combined EMI and ESD protection for single-pair high-speed signals. The 6-UFDFN package offers a small footprint suitable for dense PCB layouts. Consider the 100 mA current rating and 6 Ohm DC resistance to ensure compatibility with the target data line impedance and power requirements. Verify that the >750 MHz attenuation meets the specific EMI standards for the intended electronic equipment.

Common Mode Chokes Part Context

This component belongs to the EMI804x series from onsemi, which focuses on protecting sensitive data lines from noise and static discharge. The EMI8041 variant specifically targets single-pair configurations, distinguishing it from multi-pair counterparts like the EMI8042. The series is engineered for consumer electronics where signal integrity and component count reduction are critical design factors.

Common Mode Chokes Replacement Considerations

Public sources indicate the EMI8041BMUTAG is discontinued. Potential alternatives should be sought within the same EMI filter family or comparable single-pair solutions from other manufacturers. Verify pinout compatibility and electrical parameters such as capacitance and attenuation curves before substitution.
