2 Line Common Mode Choke Surface Mount 100mA DCR 3Ohm (Typ) , -55C ~ 125C The ECMF2-40A100N6 and ECMF4-40A100N10 are highly integrated common mode filters designed to suppress EMI/RFI common mode noise on high speed differential serial buses like HDMI 2.1, HDMI 2.0, HDMI1.4, USB4, USB 3.2 Gen 2, USB 2.0, ethernet, MIPI, Display Port and other high speed serial interfaces. They have a very large differential bandwidth to comply with these standards and can also protect and filter one or two differential lanes. 10.7 GHz differential bandwidth to comply with HDMI 2.1, HDMI 2.0, HDMI 1.4, USB4, USB 3.2 Gen2, USB 2.0, MIPI, Display port 2.0, etc. • High common mode attenuation on WLAN frequencies: – -15 dB at 2.4 GHz – -21 dB at 5.0 GHz – -17 dB at 6.0 GHz • Low serial resistance: 3.0 Ω • Very low PCB space consumption • Thin package: 0.5 mm max. • High reduction of parasitic elements through integration • Lead free and RoHS package • Exceeds IEC 61000-4-2 level 4 standard: – Contact discharge: ◦ ±9 kV (contact discharge, ECMF2-40A100N6) ◦ ±10 kV (contact discharge, ECMF4-40A100N10) – Air discharge: ◦ ±20 kV (air discharge, ECMF2-40A100N6) ◦ ±25 kV (air discharge, ECMF4-40A100N10)

2 Line Common Mode Choke Surface Mount 90 Ohms @ 100 MHz 400mA DCR 190mOhm The ACM2012-900-2P-T002, manufactured by TDK, is a 2-line common mode filter that helps reduce electromagnetic interference (EMI) and radio-frequency interference (RFI) in electronic systems. It is built using a wire-wound chip structure and optimized for high-speed differential signals while maintaining low impact on the desired signal. Key Characteristics Component Type: Common Mode Choke / EMI Filter Lines: 2-line (for differential signal pairs) Impedance: 90 Ω @ 100 MHz Current Rating: up to 400 mA DC Resistance: ~190 mΩ max Voltage Rating: up to 50 V Package Size: 0805 (2.0 × 1.2 mm) Mounting: Surface Mount (SMD) Function Suppresses common-mode noise on signal lines Maintains low differential impedance, so signal integrity is preserved Helps systems pass EMI/EMC compliance In simple terms: It filters out noise without affecting the actual data signal.
