Common Mode Chokes datasheet and documents for ECMF4-40A100N10

ECMF4-40A100N10

Common Mode Chokes Overview

The ECMF4-40A100N10 is a highly integrated common mode filter with ESD protection designed for high-speed differential serial buses. It features four data lines and operates in a µQFN-10 package. The component provides a typical DC resistance (DCR) of 3 Ohms and supports a maximum current of 100mA. It offers a differential bandwidth of 10.7 GHz, ensuring compliance with HDMI 2.1, USB4, and DisplayPort standards.

Common Mode Chokes Feature Summary

Integrates common mode filtering with electrostatic discharge protection to suppress EMI/RFI noise on high-speed differential lines.
Provides high-frequency performance suitable for modern video and data interfaces requiring wide bandwidth.
Utilizes a compact surface-mount package to minimize PCB footprint while maintaining signal integrity.

Common Mode Chokes Applications

DisplayPort interfaces
HDMI connections
USB Type-C and USB4 links

Common Mode Chokes Procurement Notes

Verify the specific ordering suffix and marking code against the manufacturer's latest datasheet to ensure correct part identification. Confirm that the µQFN-10 footprint matches your PCB design requirements. Check for any RoHS or REACH compliance documentation relevant to your region before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when designing circuits that require both ESD protection and common mode noise suppression for four-line differential signals. Ensure the 10.7 GHz bandwidth meets the highest frequency requirements of your target interface standard. Verify that the 3 Ohm DCR does not introduce excessive insertion loss for your specific application constraints.

Common Mode Chokes Part Context

This device belongs to STMicroelectronics' ECMF series of passive filters. These components are engineered specifically for protecting sensitive high-speed digital interfaces from electromagnetic interference and static discharge events. The series includes variants with different line counts and package options to suit various board space and performance needs.

Common Mode Chokes Replacement Considerations

Direct substitutes within the same family include the ECMF2-40A100N6 for two-line applications. Verify pin compatibility and electrical specifications before swapping with other manufacturers' common mode chokes. Ensure any replacement maintains the required 10.7 GHz bandwidth and ESD protection levels.
