LAN transformers and common mode inductor
27 February 2019, Passive Components

Bourns’ inductive components product line is introducing the Model SM453229-231N7Y and SM453229-381N7Y chip LAN 10/100/1000 Base-T transformers.

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. The SRF2012A-801Y common mode chip inductor pairs with the LAN transformer to provide EMI suppression.

Both transformers are compliant with IEEE 802.3 and the SM453229-231N7Y is PoE+ capable. They are available in a 4,7 x 3,2 x 2,9 mm package size with an operating temperature range of -40°C to +85°C.
