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. Unlike conventional LAN magnetics constructed with multiple toroidal core transformers and common mode chokes in a single module, the Chip LAN transformer is a discrete, centre-trapped component wound on a drum core and capped with a ferrite plate to emulate the outcome of the close magnetic path of a toroid core.


Both transformers are offered in a 4.7mm x 3.2mm x 2.9mm package size with an operating temperature range between -40C to +85C. The devices are RoHS compliant.


The devices are ideal for application in LAN interfaces for a mixture of telecommunication and network devices.
