Description

Technical Field

[0001] The utility model relates to the technical field of inductors, and particularly relates to an inductor integrating differential mode and common mode. Background Technique

[0002] Inductance is a property of a closed loop and is a physical quantity. When current passes through a coil, a magnetic field induction is formed in the coil, and the induced magnetic field will generate an induced current to resist the current passing through the coil. It is a circuit parameter that describes the effect of induced electromotive force caused by the change of coil current in the same coil or in another coil. Inductance is the general term for self-inductance and mutual inductance, and the device that provides inductance is called an inductor.

[0003] When the existing inductor integrating differential mode and common mode is designed, most of them weld the common mode inductor and the differential mode inductor on the mounting base. Therefore, when the common mode inductor or the differential mode inductor fails and needs to be repaired and replaced, it is not convenient to operate, which brings inconvenience to the installation of the inductor integrating differential mode and common mode. Therefore, we propose an inductor integrating differential mode and common mode. Content of the Utility Model
