Magnetic module and method of making the same and electrical connector including the magnetic module

A magnetic module comprising:

• a magnetic core;
• and
• a plurality of enameled wires wound on the magnetic core, the enameled wire being wound on the magnetic core to form a primary coil and a secondary coil, the primary coil including a first group of enameled wires and a second group of enameled wires, the secondary coil including a third group of only one enameled wire and a fourth group of only one enameled wire, wherein
• the respective parts of the first group of enameled wires and the fourth group of only one enameled wire wound around the magnetic core are twisted together to form a first stranded wire, the respective parts of the second group of enameled wires and the third group of only one enameled wire wound around the magnetic core are twisted together to form a second stranded wire, and the first stranded wire and the second stranded wire are twisted together to form a total stranded wire;
• the first group of enameled wires and the second group of enameled wires respectively form an input end, an output end of the primary coil, and a secondary center tap, the third group of only one enameled wire and the fourth group of only one enameled wire respectively form an input end, an output end of the secondary coil, and a secondary center tap;
• and
• each of the first group of enameled wires and the second group of enameled wires has four enameled wires.
