ST’s common-mode filters for Automotive applications are qualified as per AEC-Q101 and are compliant with standards IEC 61000-4-2 and ISO 10605.

Designed to avoid RF antenna desense in applications where the high-speed differential links generate radiated noise at frequencies received by the RF antenna, they are specifically intended for non-shielded cables (UTP Unshielded Twisted Pair) often used in HDBaseT and IEEE 1000Base-T1 connectivity solutions for digital video and audio, Ethernet, and other control communications.

They are useful in SerDes (serializer/deserializer) applications including FPD-link, GMSL, and MIPI DSI or CSI to avoid radiation in vehicle-to-everything (V2X) (5.9 GHz) and Global Navigation Satellite System (GPS, Glonass, BeiDou, Galileo, and IRNSS) frequencies.

They help to ensure a successful certification for:

  • CISPR-25, international standard for radio disturbance characteristics
  • 2004/104/EC European standard for radiated emission and immunity
  • SAE J1113/41 for North America markets
