Sunel season deals:network transformers china,transformer brand direct Sunel new transformer co., LTD network transformer through the conversion of the electromagnetic field is coupled to the other end of the network cable connections. This will not only between the cable and the PHY is no physical connection for the transmission of the signal, cut off the DC component of the signal, but also in different devices 0V level to transfer data, the current on each wire is pair of conductors in the opposite direction to transmit. If that is uniform winding of the wire, the opposite current will produce the same size, the reverse polarization of the magnetic field, making the output cancel each other. network transformer is in the signal cables or power cords in series common mode choke between the wires in parallel with the capacitor form an LC-filter to filter, filter common mode conducted noise, use a shielded cable or flat cable in the adjacent return current conductor and the transmission signal current, the loop area is reduced. Sunel new transformer co., LTD network transformer flows through the wire of each differential mode and common mode current caused by the different emission levels, differential mode current caused by the noise emissions is small, so the noise is dominated by the common mode current decision.
