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.
