In the reference schematic of an Ethernet transceiver, I noticed that the chassis ground is connected to system GND by 1nF/2kV Capacktor(C24). What is the purpose of doing this?
The connector(J1B121ZCCD) contains transformer.
Because someone has pointed that my question is duplicate, I will explain. My question is that why the 2kV capacitor is there, and not why it is 2kV.
