S558-5500-72 Power/Circuit SMD Ethernet Magnetic Transformer

Description:

The products are mainly used in: high-performance digital switches; SDH / ATM transmission equipment; ISDN, ADSL, VDSL, POE power equipment integrated service digital equipment; FILT fiber loop equipment; Ethernet switches, etc., such as Yutai Electronics' YL18-2050S , YL18-3002S, etc. are more common!
The data pump is a device that is available on consumer PCI network cards. The data pump is also called a network transformer or a network isolation transformer.
It has two main functions on a network card. One is to transmit data. It couples the differential signals sent by the PHY with differential mode.
The coil is coupled and filtered to enhance the signal, and is coupled to the other end of the connection network cable of different levels through the conversion of the electromagnetic field;
It is to isolate the different levels between different network devices connected to the network cable to prevent different voltage transmission through the network cable from damaging the device. Except this
In addition, data mercury can also play a certain lightning protection role on the device.
