Würth Elektronik Ethernet Solutions

Würth Elektronik offers multiple Ethernet solutions, including LAN transformers and modular jack connectors. The WE-LAN transformer series is designed with at least one transformer and one common mode choke in each channel. The LAN transformer portfolio consists of the WE-LAN series with Power over Ethernet (PoE) up to 150W and speeds up to 1Gbit/s, the WE-LAN 10G series with 10G Base-T and PoE(+) over four pairs up to 150W, and the WE-LAN AQ series, which is manufactured by a fully automated process with Ethernet speeds up to 1Gbit/s.

Würth Elektronik also offers the WR-MJ modular jack connectors ideal for local data communication. The WR-MJ series is available in various possibilities, ranging from plastic to shielded versions in vertical, horizontal, 45°, and 47.5° orientations. The jack design is in accordance with FCC regulations and compatible with standards IEEE s IEEE 802.3u, 802.3z (8P8C– RJ45) and PoE compatible according to IEEE 802.3af, 802.3at (8P8C–RJ45).

Another Würth Elektronik solution is the WE-RJ45 LAN transformer series, which is built with an RJ45 connector and an integrated transformer / common mode choke. The WE-RJ45 transformers are available in multiple configurations, THT or SMT, and with or without LEDs. The WE-RJ45 LAN series features PoE up to 50W and speeds up to 10Gbit/s.
