ECMF4-2459A6M10Y

Common Mode Chokes Overview

The ECMF4-2459A6M10Y is an integrated automotive common mode filter with built-in ESD protection, designed for HDMI 2.0/2.1, DisplayPort, USB 3.2, MIPI, FPD Link III, and GMSL buses. It features a 9 GHz differential bandwidth and meets AEC-Q101 standards. The device suppresses EMI/RFI noise while providing ISO 10605 compliant ESD protection at the connector side. Packaged in a QFN-10L format (2.6 x 1.35 mm) with wettable flanks for automated optical inspection, it occupies only 3.5 mm² of PCB area and has a thickness of 0.75 mm.

Common Mode Chokes Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors or direct channels. Confirm the specific suffix matches the required specifications. Ensure storage conditions adhere to moisture sensitivity levels defined in the datasheet. Check for RoHS compliance status relative to your manufacturing timeline. Validate that the QFN-10L footprint aligns with your PCB design constraints before finalizing orders.

Common Mode Chokes Selection Notes

Select this component when designing for high-bandwidth automotive video and data transmission where space is limited. It serves as a direct replacement for discrete common mode chokes or LTCC filters. Choose this part if ISO 10605 ESD protection is required on the connector side without additional components. Ensure the 9 GHz bandwidth meets the signal integrity requirements of HDMI 2.1 or USB 3.2 applications.

Common Mode Chokes Part Context

This device belongs to STMicroelectronics' ECMF portfolio of integrated common mode filters. It is engineered specifically for automotive infotainment and advanced driver-assistance systems (ADAS). The series combines filtering and ESD suppression into a single compact package, reducing board complexity compared to discrete solutions.

Common Mode Chokes Replacement Considerations

The ECMF04-4HSM10Y is listed as obsolete with the ECMF4-2459A6M10Y recommended as a substitute. Note that the replacement offers significantly higher bandwidth (9 GHz vs 2.2 GHz) and supports newer standards like HDMI 2.1 and USB 3.2. Verify pin compatibility and electrical parameter differences during migration.
