ECMF04-4HSWM10

Common Mode Chokes Overview

The ECMF04-4HSWM10 is a highly integrated common mode filter designed to suppress EMI/RFI common mode noise on high-speed differential serial buses. It supports interfaces including HDMI Full HD, MIPI, Display Port, USB2.0, and USB3.2 Gen 1. The device features a large differential bandwidth of 4.2 GHz and provides high common mode attenuation at WLAN frequencies, specifically 28 dB at 2.4 GHz and -16 dB at 5.0 GHz. It offers robust ESD protection rated at ±15 kV (air discharge) and ±8 kV (contact discharge). The component utilizes a thin package with a maximum height of 0.55 mm to minimize PCB space consumption.

Common Mode Chokes Procurement Notes

Verify the specific revision and packaging details against the official STMicroelectronics datasheet before procurement. Confirm that the QFN-10L package dimensions and pinout match your PCB footprint requirements. Ensure the selected variant meets the thermal and mechanical specifications for your intended operating environment. Cross-reference the part number with the manufacturer's current product status to avoid obsolete components.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring simultaneous ESD protection and common mode noise filtering for high-speed data lines. The 4.2 GHz bandwidth makes it suitable for signals up to HDMI Full HD and USB3.2 Gen 1 speeds. Consider the low parasitic elements and small footprint if board real estate is limited. Verify compatibility with the specific interface standard being implemented to ensure adequate signal integrity.
