摘要： An electromagnetic filter for operating in common and differential mode is provided. The filter comprises a toroidal-like magnetic core; first and second separated coils wound around the magnetic core, the first and second coils and the magnetic core being configured to provide a common mode filter. The filter also has a third coil that surrounds the magnetic core and the first and second coils and arranged around a Z axis that is coaxial with an inner hollow part of the magnetic core, the third coil being configured to provide a filter operating in differential mode. Two sheets are also arranged between opposite external faces of a capacitor to thermally isolate the capacitor from the coils, the capacitor and sheets being arranged inside the inner hollow part. A layer of a thermal conductive magnetic compound encloses all the elements to increase leakage inductance and to enclose a magnetic field generated by the third coil.

摘要： A magnetic core includes a winding core portion and two flange portions. The winding core portion is an octagonal cylinder. Two flange portions are respectively provided to two ends of the octagonal cylinder. Each of two flange portions has a top surface. One end of each of plural winding wires is connected to the top surface of one of two flange portions, and the other end of each of the winding wires is connected to the top surface of the other one of two flange portions. The octagonal cylinder has a first lateral surface and a second lateral surface adjacent to each other. The first lateral surface of the octagonal cylinder is parallel to the top surface of each of two flange portions. The area of the first lateral surface of the octagonal cylinder is less than the area of the second lateral surface of the octagonal cylinder.

摘要： An inductor device may include a first electrically conductive path and a second electrically conductive path. The first electrically conductive path may extend from a first terminal of the inductor device to a second terminal of the inductor device. The second electrically conductive path may extend from a third terminal of the inductor device to a fourth terminal of the inductor device. The second electrically conductive path may be magnetically coupled to the first electrically conductive path. Each of the third terminal and the fourth terminal may be offset with respect to a virtual axis extending through the first terminal and the second terminal.

摘要： This application provides a power inductor, a preparation method of a power inductor, and a system in package module, and the power inductor is applied to the system in package module. The power inductor includes a winding and a metal magnetic powder core. The metal magnetic powder core is configured to support the winding, and the winding uses a metal conductive sheet. During assembly, the metal magnetic powder core is integrated with the winding through pressing, the metal magnetic powder core wraps the winding, and the metal magnetic powder core is insulated from the winding. The winding has a first pin and a second pin, and the first pin and the second pin are exposed on different surfaces of the metal magnetic powder core. Pins are separately disposed on two different surfaces of the power inductor, so that the power inductor can match a system in package module in which components are arranged in different directions. Therefore, disposing of the inductor is facilitated. In addition, the winding is formed by integrally pressing the metal conductive sheet and the metal magnetic powder core, so that inductance of the power inductor is increased, loss of the inductor is reduced, and miniaturization of the inductor is improved.
