The LAN transformer helps prevent electromagnetic interference (EMI) by providing electrical isolation and filtering. It also matches impedance levels, adjusts signal timings, and provides common-mode noise rejection. This enables reliable and efficient data transmission over the network.
LAN transformers are commonly used in Ethernet technologies, such as 10BASE-T, 100BASE-TX, and 1000BASE-T, where they play a crucial role in facilitating the transmission of data packets between network devices.
