Product details
Overview
ECMF4-2459A6M10Y from STMicroelectronics is an AEC-Q101-qualified automotive common mode filter with integrated ESD protection, designed for HDMI 2.0/2.1, USB 3.2 Gen1/Gen2, MIPI, DisplayPort, FPD-Link III, and GMSL differential high-speed buses. It provides 9 GHz differential bandwidth, -34 dB common-mode attenuation at 2.4 GHz, and clamps to 18.5 V under 8 kV ISO 10605 contact discharge.
For engineers reviewing the ECMF4-2459A6M10Y datasheet, ECMF4-2459A6M10Y pinout, ECMF4-2459A6M10Y application, or ECMF4-2459A6M10Y equivalent, key selection criteria include differential bandwidth compliance with HDMI 2.1 (12 Gbps), common-mode noise suppression across LTE/GPS/Wi-Fi/V2X bands, wettable-flank QFN-10L package compatibility with AOI, and integrated ±8 kV/±15 kV ESD robustness per ISO 10605.
Technical Context
This device integrates dual-channel common-mode chokes with bidirectional ESD protection diodes on both connector-side and IC-side terminals. Its symmetrical layout supports two independent differential pairs (D1+/D1− and D2+/D2−), each with matched impedance and low insertion loss up to 9 GHz.
The filter achieves broadband common-mode rejection via coupled inductor architecture while maintaining differential signal integrity - verified by eye diagram improvement in HDMI 2.1 (12 Gbps) and USB 3.2 Gen2 (10 Gbps) test setups with worst-case channel models and equalization.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar common mode filter with ESD protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD4E05U06DQAR | Single-channel, 5.5 V VBR, lower bandwidth (3 GHz), no wettable flank | Suitable for USB 2.0 or low-speed I²C, not HDMI 2.1 or GMSL | Select only for cost-sensitive non-automotive designs with ≤480 Mbps data rates |
| CM1293A-04SO | Quad-channel, 6.5 V VBR, 6 GHz bandwidth, QFN-16 package, no AEC-Q101 rating | Targeted at industrial displays and medical monitors, not automotive ECU environments | Choose when needing four channels in one package but can waive automotive qualification and 9 GHz support |
Compared with TPD4E05U06DQAR and CM1293A-04SO, ECMF4-2459A6M10Y uniquely delivers AEC-Q101 qualification, 9 GHz bandwidth, and wettable flank in a dual-channel QFN-10L - making it the only option qualified for production automotive HDMI 2.1 and GMSL systems requiring zero-defect solder joint inspection.

FAQ
What is the maximum data rate supported by ECMF4-2459A6M10Y?
ECMF4-2459A6M10Y supports up to 12 Gbps differential data rates, validated via HDMI 2.1 eye diagrams with worst-case cable models and CTLE/DFE equalization. Its 9 GHz differential bandwidth ensures minimal intersymbol interference and meets USB 3.2 Gen2 (10 Gbps) and FPD-Link III (4.16 Gbps) requirements without signal degradation.
Does ECMF4-2459A6M10Y require external bias or control signals?
No. ECMF4-2459A6M10Y is a passive integrated filter with no active circuitry, supply pins, or configuration interfaces. It operates transparently in-line with differential signal paths and requires no external power, enabling drop-in replacement of discrete chokes and ESD diodes without firmware or layout changes.
How does the wettable flank feature improve manufacturing yield?
The wettable flank design exposes solderable metal along the vertical sidewall of each QFN lead, allowing automated optical inspection (AOI) systems to verify solder fillet formation and joint completeness without X-ray imaging. This reduces escape of insufficient-solder defects in high-volume automotive PCB assembly lines.
Can ECMF4-2459A6M10Y be used in non-automotive applications?
Yes - its electrical performance (9 GHz bandwidth, ±15 kV ESD, -55 °C to +125 °C operation) applies to industrial and premium consumer equipment. However, AEC-Q101 qualification adds cost and test overhead; for non-automotive use, ST offers pin-compatible variants like ECMF4-2459A6M10 without automotive screening if full qualification is unnecessary.
