How common mode choke works

WebThe role of common mode filters is to selectively remove noise propagating in common mode while allowing signals, which flow in differential mode, to pass. These noise suppression components are widely used in high-speed digital interfaces like USB, IEEE 1394, HDMI, and DisplayPort. Web6 de dez. de 2024 · 6 Dec 2024. Common mode choke coils (CMCC) are filters that reduce common mode noise that is problematic in differential transmission lines (non-automotive use: USB, HDMI, Mipi, etc.; automotive use: CAN, CAN-FD, 100Base-T1, 1000Base-T1, SerDes, A2B®, etc.), power lines, and audio lines.
