ECMF04-4HSWM10Y

Common Mode Chokes Overview

The ECMF04-4HSWM10Y is an automotive-grade integrated common mode filter with ESD protection, designed for HDMI 1.4, USB 3.1, and MIPI buses. It features a 3.5 GHz differential bandwidth and meets AEC-Q101 standards. Common mode attenuation values are -13 dB at 0.7 GHz, -24 dB at 1.5 GHz, -30 dB at 2.4 GHz, -26 dB at 2.7 GHz, and -16 dB at 5.0 GHz. The device operates within a temperature range of -55°C to 125°C, has a maximum rated current of 100mA, and utilizes a QFN-10L package measuring 3.5 mm² area and 0.75 mm height.

Common Mode Chokes Procurement Notes

Verify the specific suffix 'M' in the part number corresponds to the wettable side variant when sourcing. Confirm AEC-Q101 qualification status for automotive deployment requirements. Ensure compatibility with automated visual inspection processes due to the specific package design. Validate that the 100mA current rating aligns with the target circuit's operational limits before integration.

Common Mode Chokes Selection Notes

Select this component for applications requiring simultaneous ESD protection and high-frequency noise suppression in space-constrained designs. The integrated nature eliminates the need for separate filters and protection diodes. Consider the 0.75 mm profile for thin form factor devices. Ensure the 3.5 GHz bandwidth suffices for the highest frequency components of the signal being protected.

Common Mode Chokes Part Context

This component belongs to STMicroelectronics' ECMF series of automotive common mode filters. It represents a consolidation of EMI filtering and electrostatic discharge protection into a single surface-mount device. The series targets high-speed digital interfaces where signal integrity and component reliability under harsh automotive conditions are critical.
