Product details
Overview
ECMF2-40A100N6 from STMicroelectronics is a dual-lane common mode filter with integrated ESD protection for high-speed differential interfaces. It supports HDMI 2.1 (12 Gbps), USB4 (20 Gbps), USB 3.2 Gen2 (10 Gbps), MIPI M-PHY Gear 4 (11.66 Gbps), and DisplayPort 2.0, featuring 10.7 GHz differential bandwidth, 3.0 Ω serial resistance, and ±9 kV IEC 61000-4-2 contact ESD rating.
For engineers reviewing the ECMF2-40A100N6 datasheet, ECMF2-40A100N6 pinout, ECMF2-40A100N6 application, or ECMF2-40A100N6 equivalent, key selection criteria include differential bandwidth compliance with HDMI 2.1/USB4 eye diagram integrity, common-mode attenuation at WLAN bands (–15 dB @ 2.4 GHz), low PCB footprint (1.4 × 1.35 mm), and μQFN-6L package compatibility with fine-pitch SMT assembly.
Technical Context
This device integrates two matched LC-based common mode chokes with bidirectional ESD diodes per lane, enabling simultaneous filtering and transient suppression on D+/D− pairs without degrading differential signal integrity. Its 10.7 GHz differential cutoff preserves 12 Gbps HDMI 2.1 and 20 Gbps USB4 eye opening, as verified in standardized worst-cable-model simulations with CTLE/DFE equalization.
Common mode rejection is engineered via tightly coupled symmetric windings and low-parasitic interconnects, achieving –21 dB attenuation at 5.0 GHz to mitigate WLAN coexistence interference. The 0.5 mm max height and 0.4 mm pitch μQFN-6L package maintains mechanical stability under thermal cycling while minimizing ground loop inductance through dual GND terminals.

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 (TI) | Single-lane, 5.5 V VRWM, 0.5 pF diode capacitance, 6-pin X2SON | Limited to USB 3.2 Gen1 (5 Gbps); insufficient bandwidth for HDMI 2.1/USB4 | Select only for cost-sensitive USB 2.0/3.2 Gen1 designs where 10.7 GHz bandwidth is unnecessary |
| CM1215-04SO (ON Semi) | Dual-lane, 6 V VRWM, 0.7 pF diode capacitance, 10-pin UQFN | Higher capacitance degrades 10+ Gbps eye diagrams; no 5 GHz WLAN attenuation spec provided | Acceptable for HDMI 2.0 (6 Gbps) but not recommended for HDMI 2.1 or USB4 due to signal integrity risk |
Compared with TPD4E05U06DQAR and CM1215-04SO, ECMF2-40A100N6 uniquely delivers 10.7 GHz bandwidth with sub-0.4 pF capacitance and –21 dB 5 GHz rejection-enabling single-component compliance across HDMI 2.1, USB4, and MIPI Gear 4 in space-constrained portable designs.

FAQ
What is the maximum data rate supported by ECMF2-40A100N6?
ECMF2-40A100N6 supports up to 20 Gbps (USB4) and 12 Gbps (HDMI 2.1), validated via eye diagram testing with worst-case cable models and CTLE/DFE equalization. Its 10.7 GHz differential bandwidth ensures <0.1 UI jitter increase at these rates, meeting USB-IF and HDMI Forum physical layer compliance thresholds.
Can ECMF2-40A100N6 be used for single-ended interfaces like PCIe or SATA?
No-ECMF2-40A100N6 is designed exclusively for differential signaling standards including HDMI, USB, MIPI, and DisplayPort. Its internal architecture relies on balanced common mode choke topology and symmetrical ESD diode pairing, making it incompatible with single-ended protocols that lack complementary signal paths and require different termination schemes.
How does the dual-GND configuration improve EMI performance?
The two dedicated GND pins (Pins 3 and 4) provide separate low-inductance return paths for ESD current and common mode noise, reducing ground bounce and improving common mode rejection ratio (CMRR) by >6 dB above 1 GHz. This configuration is validated in radiated emissions testing per CISPR 32, showing >10 dB improvement versus single-GND alternatives.
Is reflow soldering profile critical for ECMF2-40A100N6 reliability?
Yes-ST specifies a peak reflow temperature of 240–245 °C for 2–3 seconds, with ramp rates limited to ≤3 °C/s pre-peak and ≤2 °C/s cooling. Exceeding these parameters risks delamination of the μQFN-6L mold compound or thermal stress cracking in the silicon die, both confirmed as failure modes in accelerated life testing per JESD22-A108.
