Product details
Overview
ECMF4-2450A17M10 from STMicroelectronics is a µQFN-10L common mode filter with integrated ESD protection for high-speed HDMI differential lanes, delivering -23 dB attenuation at 2.4 GHz and -32 dB at 5.0 GHz, 1.7 GHz differential cut-off frequency, 5.5 Ω DC resistance, and 8 kV IEC 61000-4-2 contact ESD rating-deployed in HDMI 1.4 streaming boxes and game consoles.
For engineers reviewing the ECMF4-2450A17M10 datasheet, ECMF4-2450A17M10 pinout, ECMF4-2450A17M10 application, or ECMF4-2450A17M10 equivalent, key selection criteria include differential-mode bandwidth (1.7 GHz), dual-lane ESD clamping voltage (12.9 V @ 16 A), GND-referenced diode capacitance (0.35–0.45 pF @ 2.5–6 GHz), and µQFN-10L footprint compatibility with HDMI 2.0 layout constraints.
Technical Context
This device integrates two matched differential LC low-pass filters with back-to-back ESD diodes per lane, enabling simultaneous suppression of both differential-mode noise (e.g., HDMI TMDS jitter) and common-mode noise (e.g., RF coupling from WLAN antennas). Its symmetrical pinout supports bidirectional signal routing between connector and ASIC sides.
The internal architecture uses monolithic silicon-based ESD protection with dynamic resistance of 0.48 Ω (D+/D− to GND) and 0.96 Ω (GND to D+/D−), ensuring fast transient response (<30 ns) while maintaining <5.5 Ω total series resistance across each signal path to minimize insertion loss.
Key Specifications

|---|---|
| Differential attenuation | -23 dB @ 2.4 GHz, -32 dB @ 5.0 GHz - suppresses WLAN interference on HDMI lanes without degrading eye diagram integrity |

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, 0.5 pF diode capacitance, 12 V clamping, SOT-563 package | Requires four devices for dual-lane HDMI; higher board area and routing complexity | Prefer when discrete layout control or legacy footprint reuse is required |
| CM1213A-04SO | Quad-channel, 0.8 pF capacitance, -15 dB @ 2.4 GHz, SOIC-14 package | Larger footprint (5.0 × 6.2 mm); lower attenuation at 5 GHz; no µQFN thin-profile option | Prefer for industrial HDMI monitors where thermal derating and manual rework are priorities |
Compared with TPD4E05U06DQAR and CM1213A-04SO, ECMF4-2450A17M10 delivers superior high-frequency attenuation (-32 dB @ 5 GHz vs. ≤-15 dB), lower parasitic capacitance (0.4 pF vs. ≥0.5 pF), and 60% smaller PCB area-making it optimal for space-constrained consumer HDMI endpoints.

FAQ
What is the maximum data rate supported by ECMF4-2450A17M10?
The device supports HDMI 2.0 data rates up to 6 Gbps, validated via eye diagram testing at 2.228 Gbps (HDMI 1.4) and 1.485 Gbps. Its 1.7 GHz -3 dB differential cut-off frequency exceeds the Nyquist frequency of these signals, ensuring minimal amplitude and phase distortion across the full bandwidth.
Can ECMF4-2450A17M10 be used for USB 3.0 interfaces?
No-ECMF4-2450A17M10 is optimized for HDMI's 100 Ω differential impedance and 2.4/5.0 GHz WLAN rejection profile. USB 3.0 requires 90 Ω impedance matching and different ESD clamping dynamics; ST recommends the USBULN6-2P6 for USB 3.0 SuperSpeed applications.
How does the dual-side pinout affect PCB layout?
Pins 1–5 route signals from the HDMI connector side; Pins 6–10 route to the SoC side. This bidirectional layout allows placement directly between connector and ASIC with minimal trace stubs, reducing reflections and maintaining controlled impedance across both directions without vias or layer transitions.
Is reflow soldering compatible with µQFN-10L package?
Yes-the µQFN-10L package is qualified for standard lead-free reflow per IPC/JEDEC J-STD-020. ST specifies a peak temperature of 260 °C, ramp rate ≤3 °C/s, and dwell time at >217 °C of 60–150 seconds; recommended stencil aperture is 0.12 mm with 5–7 mil particle-size solder paste.
