48Pin Ethernet Lan Transformer SMD 1000Base-T Magnetic Network Filter IC Module

Network LAN Transformer SMD 10/100/1000 Base-T Magnetics

1. One is to transmit data. It filters the differential signal sent by the PHY with the differential mode coupling coil coupling to enhance the signal, and couples it to the other end of the connecting network cable of different levels through the conversion of the electromagnetic field;

2. The second is to isolate different levels between different network devices to prevent different voltages from being transmitted through network cables and damage the devices.

In addition, data mercury can also play a certain lightning protection role for the equipment. It is mainly used in network switches, routers, network cards, and hubs for signal coupling, high-voltage isolation, impedance matching, and electromagnetic interference suppression.
