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

product description:

On the network communication motherboard, between the PHY chip and the RJ45 connector, there will be a small black square. This thing is called a network transformer. The book name is "Data Mercury". People often call it a network isolation transformer, LAN Transformers, LAN transformers, filters, etc.
