Single Pair Ethernet Products

Würth Elektronik Single Pair Ethernet Products require only one pair of wires, ensuring thinner cable diameters and reduced cost. This compact design also reduces the number of passive components on a PCB. When used with a compact connector, Single Pair Ethernet can save up to 75% PCB space, compared to current Ethernet over RJ45. Würth Elektronik Single Pair Ethernet Products offer isolation in accordance with IEC 62368-1. Typical applications for these products include Ethernet 10/100/1000 Base-T, Ethernet 2.5/5G and 10G Base-T, DC-DC converters, USB 3.1 Type C, USB 3.0, USB 2.0, HDMI, LVDS, high-speed data lines, and much more.
