Bourns SM453230-121N7YP and SM453230-231N7YP series gigabit ethernet

Bourns magnetics product line is introducing the new model SM453230-121N7YP Gigabit Ethernet / PoE+ Chip LAN 1G/2.5G/5G and model SM453230-231N7YP Gigabit Ethernet / PoE+ Chip-LAN 10G 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, center-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. The discrete transformer-common mode chip inductor arrangement offers a high degree of flexibility in a PCB layout.

The model SM453230-121N7YP and model SM453230-231N7YP Gigabit Ethernet Chip-LAN Transformers are IEEE 802.3 Ethernet compatible and PoE+ (700mA) capable, with an expanded operating temperature range of -40 to +85 °C. They are ideal for use in LAN interfaces for a variety of high-speed telecommunication and network devices.
