High-capacitance common mode choke processing circuit for network signals

The invention discloses a high-capacitance common-mode inductor processing circuit for network signals, which is characterized in that a high-capacitance common-mode inductor for signal coupling is arranged between each two adjacent circuit channels, and at least one parasitic capacitor exists between the primary side and the secondary side of each high-capacitance common-mode inductor. An autotransformer is arranged on one side of each high-capacitance-value common mode inductor, center tap lines of the autotransformers are electrically connected and then connected to a grounding side, each high-capacitance-value common mode inductor is composed of an iron core middle column and an iron core cover plate, each iron core middle column comprises a winding part for winding a plurality of circles of wires, and the winding parts are arranged on the ground side of each high-capacitance-value common mode inductor. A plurality of circles of wires on the winding part of the iron core middle column are wound by a prese
