Common Mode Choke for Automotive Ethernet Applications



Pulse Electronics AE3003 100Base-T1 Power over Data Lines (PoDL) Common Mode Choke (CMC) is a 300mA single twisted pair device for automotive Ethernet applications. This CMC supports PoDL classes 0, 1, 2, 4, and 6. The AE3003 CMC reduces the need for a second twisted pair wire to power an end device and reduces the overall weight and cost of cabling. This CMC operates at a temperature range from -40°C to 125°C and offers high reliability. Typical applications include infotainment, Advanced Driver Assistance Systems (ADAS), body control, camera/radar, gateways, and backbone diagnostics.
