SM453230-121N7YP and SM453230-231N7YP Gigabit Ethernet/PoE+ Chip-LAN Transformers

Bourns Magnetics model SM453230-121N7YP Gigabit Ethernet/PoE+ chip LAN 1G/2.5G/5G and model SM453230-231N7YP Gigabit Ethernet/PoE+ Chip-LAN 10GBASE-T transformers are discrete, center-tapped components. Unlike traditional LAN magnetics built with multiple toroidal core transformers and common mode chokes in a single module, the SM453230-121N7YP and SM453230-231N7YP chip-LAN transformers are 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 SM453230-231N7YP Gigabit Ethernet Chip-LAN transformers are IEEE 802.3 Ethernet compatible and PoE+ (700 mA) capable with an expanded operating temperature range of -40°C to +85°C. They are ideal for use in LAN interfaces for a variety of high-speed telecommunication and network devices.
