ECMF04-4HSM10Y

Common Mode Chokes Overview

The ECMF04-4HSM10Y 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 2.2 GHz differential bandwidth and provides -20 dB attenuation at 0.7 GHz, -25 dB between 0.8-0.9 GHz, and -14 dB at 1.5 GHz. The device meets AEC-Q101 standards and ISO 10605 ESD requirements. Packaged in a compact QFN-10L format measuring 3.5 mm² area and 0.75 mm height, it supports automatic optical inspection via wettable flanks.

Common Mode Chokes Feature Summary

Integrates common mode filtering and ESD protection to suppress EMI/RFI noise on high-speed differential serial buses.
Provides deep attenuation in LTE, GSM, and GPS frequency bands to prevent interference with cellular and navigation antennas.
Features wettable side terminals compatible with automated visual inspection processes.

Common Mode Chokes Applications

HDMI 1.4 interface signal lines
USB 3.1 data connections
MIPI high-speed bus links

Common Mode Chokes Procurement Notes

This component is officially classified as Obsolete by the manufacturer. Procurement should focus on verified replacement part numbers rather than sourcing this specific obsolete unit. Verify that any substitute maintains the required automotive qualification and package compatibility for your design.

Common Mode Chokes Selection Notes

Select this component only if legacy designs require its specific electrical characteristics and form factor. Due to its obsolete status, new designs must utilize recommended alternatives. Ensure the replacement part matches the QFN-10L footprint and meets the same AEC-Q101 reliability standards for automotive environments.

Common Mode Chokes Part Context

The ECMF04-4HSM10Y belongs to STMicroelectronics' ECMF series of integrated filters. These devices replace discrete common mode chokes and LTCC components, offering reduced PCB space consumption and lower parasitic elements through high integration. The series targets automotive communication systems requiring robust noise suppression and electrostatic discharge protection.

Common Mode Chokes Replacement Considerations

STMicroelectronics recommends the ECMF4-2459A6M10Y as a direct replacement for this obsolete part. Verify pinout compatibility and electrical specifications before substitution.
