The Bourns Electronics 10/100/1000 base-T chip LAN transformer unlike traditional LAN magnetics built with multiple toroidal core transformers and common mode chokes assembled in a single module, this 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.
IEEE 802.3 Ethernet compatible
Compatible with 10/100/1000 BASE-T
Discrete transformers and common mode chokes for flexible PCB layout
Expanded temperature range of -40 to +105 °C
AEC-Q200 Compliant and halogen free
