Product details

Overview

ECMF04-4HSWM10Y from STMicroelectronics is an AEC-Q101-qualified integrated common mode filter with integrated ESD protection, designed for HDMI 2.0/1.4, USB 3.1, MIPI, and LVDS differential buses. It delivers 3.5 GHz differential bandwidth, -24 dB common-mode attenuation at 1.5 GHz, and clamps to 27 V under 8 kV ISO 10605 contact discharge.

For engineers reviewing the ECMF04-4HSWM10Y datasheet, ECMF04-4HSWM10Y pinout, ECMF04-4HSWM10Y application, or ECMF04-4HSWM10Y equivalent, key selection criteria include differential bandwidth compliance with HDMI 2.0 (5.94 Gbps), common-mode noise suppression across LTE/GPS bands, wettable flank QFN-10L package compatibility with AOI, and integrated ±15 kV air/±8 kV contact ESD protection per ISO 10605.

Technical Context

This device integrates two independent common-mode chokes (D1+/D1− and D2+/D2− paths) with bidirectional ESD protection diodes on both connector-side terminals. Its differential impedance is matched to 100 Ω, and common-mode impedance is tuned for 50 Ω systems, enabling clean signal integrity in high-speed serial links without degrading eye diagrams.

The QFN-10L package features wettable flanks for solder joint inspection and supports reflow per J-STD-020 MSL Level 1. Electrical behavior is characterized up to 3.5 GHz (SDD21 = −3 dB), with DC resistance ≤5.5 Ω per differential path and leakage current ≤100 nA at 3 V standoff voltage.

Key Specifications

Parameter	Value and Actual Design Meaning
Differential Bandwidth	3.5 GHz (SDD21 = −3 dB): ensures full compliance with HDMI 2.0 (5.94 Gbps) and USB 3.1 (5 Gbps) data rates
Common-Mode Attenuation	−24 dB at 1.5 GHz: suppresses GPS band interference without affecting differential signal integrity
ESD Clamping Voltage	27 V at 8 kV contact discharge (ISO 10605, 150 pF/330 Ω): limits downstream IC stress during transient events
DC Resistance	5.5 Ω max per differential pair: minimizes insertion loss and power dissipation in 100 mA RMS operation
Operating Temperature	−55 °C to +125 °C: supports automotive under-hood and infotainment module deployment
Package	QFN-10L, 2.6 mm × 1.35 mm × 0.75 mm: enables compact routing in space-constrained PCBs with AOI-compatible wettable flanks

Pinout & Package

ECMF04-4HSWM10Y is housed in a 10-pin QFN package (QFN-10L) with wettable flank terminations for automated optical inspection. The exposed thermal pad is connected to GND internally and must be soldered to a PCB ground plane for optimal EMI performance and thermal stability.

Pin/Terminal	Circuit Role	Design Meaning
1 (D1+ Con)	Connector-side positive terminal of Channel 1	Input for differential signal pair 1 from external interface (e.g., HDMI source connector)
2 (D1− Con)	Connector-side negative terminal of Channel 1	Completes differential path for Channel 1; carries equal-magnitude opposite-phase signal
3 (GND)	Common ground reference	Provides return path for ESD current and common-mode noise; ties internal choke shields and thermal pad
4 (D2+ Con)	Connector-side positive terminal of Channel 2	Input for second differential signal pair (e.g., USB 3.1 TX or MIPI DSI clock)
5 (D2− Con)	Connector-side negative terminal of Channel 2	Second connector-side differential input; electrically isolated from Channel 1
6 (D2− IC)	IC-side negative terminal of Channel 2	Output to SoC or controller; maintains signal polarity and impedance continuity
7 (D2+ IC)	IC-side positive terminal of Channel 2	IC-side output for Channel 2; routed directly to host processor or PHY
8 (GND)	Secondary ground terminal	Redundant GND connection to improve grounding symmetry and reduce ground loop inductance
9 (D1− IC)	IC-side negative terminal of Channel 1	Delivers filtered differential signal to host IC while preserving phase alignment
10 (D1+ IC)	IC-side positive terminal of Channel 1	Final output node for Channel 1; requires controlled 100 Ω differential trace routing

Key Features

Feature	Design Value

Equivalent & Alternatives

The following parts are listed as comparable options for similar common mode filter with integrated ESD protection applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TDK MEM2012W121RT001	Single-channel, 1.2 GHz bandwidth, no integrated ESD diodes; requires external TVS	Limited to lower-speed interfaces (≤1.5 Gbps); unsuitable for HDMI 2.0 or USB 3.1	Select only when cost sensitivity outweighs integration needs and speed requirements are ≤1 Gbps
ON Semiconductor NUF4310MUTAG	Quad-channel ESD array only; no common-mode choke function; R_DC = 0.5 Ω but no CMRR specification	Provides ESD protection only; cannot replace common-mode filtering function-requires separate choke	Use only as supplemental ESD protection alongside discrete CM chokes, not as drop-in replacement

Compared with MEM2012W121RT001 and NUF4310MUTAG, ECMF04-4HSWM10Y uniquely combines dual-channel 3.5 GHz common-mode filtering, integrated ±8 kV ESD protection, and automotive-grade reliability in one QFN-10L package-eliminating board space, BOM count, and layout complexity for HDMI/USB/MIPI designs.

FAQ

What is the maximum differential data rate supported by ECMF04-4HSWM10Y?

The device supports differential data rates up to 5.94 Gbps, as validated by HDMI 2.0 eye diagram testing (DS12859 Figures 9–10). Its 3.5 GHz differential bandwidth (SDD21 = −3 dB) ensures minimal intersymbol interference and meets USB 3.1 Gen 1 and MIPI D-PHY v2.1 timing budgets without equalization.

Does ECMF04-4HSWM10Y require external ESD protection components?

No. The device integrates bidirectional ESD protection diodes on all connector-side pins (D1+/D1−/D2+/D2−), certified to ISO 10605 Level 4 (±8 kV contact, ±15 kV air) and IEC 61000-4-2. External TVS devices are unnecessary unless system-level surge requirements exceed these ratings.

How should the exposed thermal pad be handled during PCB layout?

The exposed pad (Pin 3 and Pin 8 GND connections) must be soldered to a solid PCB ground plane using at least nine thermal vias (0.3 mm diameter, spaced ≤1 mm apart) to ensure low-inductance grounding, effective heat dissipation, and optimal common-mode noise shunting. Stencil opening per DS12859 Figure 16 is recommended.

Is ECMF04-4HSWM10Y compatible with lead-free reflow profiles?

Yes. It is qualified for lead-free reflow per J-STD-020 MSL Level 1, with peak temperature up to 245 °C (see DS12859 Figure 25). The recommended profile includes ramp-up ≤3 °C/s, soak at 150–200 °C for 60–120 s, and time above liquidus (217 °C) of 60–90 s-fully compatible with standard Pb-free SAC305 processes.
