The Bourns Electronics 10 Gb Ethernet/PoE+ chip-LAN transformer unlike traditional LAN magnetics built with multiple toroidal core transformers and common mode chokes in a single module, the chip-LAN transformer is a discrete, centre-tapped component wound on a drum core and capped with a ferrite plate to emulate the result of the close magnetic path of a toroid core. A common mode chip inductor is paired with a chip-LAN transformer to provide EMI suppression.

IEEE 802.3 Ethernet compatible
Compatible with 10G Base-T
PoE+ capable and halogen free
Discrete transformers and common mode chip inductors for flexible PCB layout
Expanded temperature range of -40 to +85 °C
