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, center-trapped 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. Bourns® Model SM453229-231N7Y and SM453229-381N7Y Chip LAN Transformers are compliant with IEEE 802.3 and the Bourns® Model SM453229-231N7Y is PoE+ capable. Both transformers are available in a 4.7 x 3.2 x 2.9 mm package size with an operating temperature range of -40 to +85 °C. They are ideal for use in LAN interfaces for a variety of telecommunication and network devices.
