Würth Elektronik WE-RJ45 10G LAN transformers

Würth Elektronik has extended its WE-RJ45 10G transformer series with four additional models. Three tab-down models join the existing Ethernet connectors with an integrated transformer in tab-up design. These models have the recess for the connector tab on the underside.

The four RJ45 integrated transformer connectors feature a low-profile package. One of the models is especially suitable for particularly flat assemblies and is inserted into a recess in the board. One model, an RJ45 with integrated transformer, is designed to optimally exploit the possibilities of Power over Ethernet: up to 100 W of power can be sent over the data line (4PPoE).

In contrast to standard RJ45 connectors with integrated transformer and common mode choke, the WE-RJ45 10G models are specified for the industrial temperature range from -40 to +85°C. They are especially suitable for 10G Base-T Ethernet applications with up to 100 m cable length, such as office and factory access points, gateways, servers, high-speed routers and switches, as well as HDBaseT. The latest models also include a transformer with a fifth channel for use with the corresponding PHY chips.
