An electrical connector ( 100 ) to be mounted on a substrate provides signal channels between a first side and a second side. The electrical connector includes a transformer ( 210 ), a common mode filter ( 327 ) and a separated filter ( 328 ). The transformer includes a first wire ( 314 ) having two opposite ends electrically connected to said first side and a second wire ( 312 ) having two opposite ends and a center tap ( 313 ). The common mode filter includes a third wire ( 322 ) and a fourth wire ( 324 ), each of the third wire ( 322 ) and the fourth wire ( 324 ) having an end respectively electrically connected to the two opposite ends of the second wire ( 312 ). The separated filter ( 328 ) includes a fifth wire ( 326 ) separated from the common mode filter ( 327 ) and the transformer ( 310 ), the fifth wire ( 326 ) having an end electrically connected to the center tap ( 313 ) of the second wire ( 312 ). Opposite ends of the third, the fourth and the fifth wires ( 322, 324, 326 ) are electrically connected to the second side.

A power over Ethernet (PoE) interface for 10GBase-T Ethernet includes at least one communication channel Ethernet interface including an autotransformer having a center tap for coupling direct current (DC) power. A combination of the geometry of the toroid core of the autotransformer and in some embodiments of a common mode choke, as well as the wire twisting, the wire distribution and the wire routing allow maximizing bandwidth up to or greater than 500 MHz for 10GBase-T performance by increasing the coupling and reducing capacitance across the wires, and results in return and insertion losses and OCL that meet anticipated standards.

High power pulse transformer

10G Ethernet transformer and manufacturing method thereof

The invention discloses a transformer (100), which comprises a magnetic core (3), and a first group of enameled wires (1) and a second group of enameled wires (2) which are wound on the magnetic core. Each group of enameled wires comprises four enameled wires. The magnetic core comprises a first part (31) and a second part (32). The first group of enameled wires (1) is only wound at the first part (31) of the magnetic core. The second group of enameled wires (2) is only wound at the second part (32) of the magnetic core. The transformer disclosed by the invention has the technical effects that the electric property is excellent and the wire winding automation is facilitated.

Transformer and manufacturing method and electric connector thereof

A component having a core, a first multi-wire bundle having primary and secondary windings wound about the core and a second multi-wire bundle having primary and secondary windings wound about the same core. In one form, the first and second bundles are wound in parallel with one another in a bifilar manner about the core. The method of winding the component allows the component to handle high current, high frequency data applications. An isolation transformer and filter circuit are also shown using the transformer and/or method of winding same.
