A common mode inductor apparatus includes a magnetic core, a first coil winding and a second coil winding. The magnetic core has a first winding zone and a second winding zone. The first coil winding is wound in three winding areas within the first winding zone, wherein two neighboring winding areas within the first winding zone are separated by a gap. The second coil winding is wound in three winding areas within the second winding zone, wherein two neighboring winding areas within the second winding zone are separated by a gap.

Common mode inductor apparatus having coil winding wound in multiple winding areas, and related winding method of common mode inductor apparatus and electromagnetic interference filter circuit

The present invention discloses an electromagnetic shielding assembly including an electromagnetic interference shielding component including a plate body and a bending portion. An included angle is formed between the plate body and the bending portion, and the plate body and the bending portion cover an input socket of a power supply. The electromagnetic interference shielding component includes at least one grounding pin disposed on the plate body or/and the bending portion and configured to ground with and screw to a housing of the power supply, and a welding pin disposed on a side of the bending portion away from the plate body and electrically connected to an auxiliary circuit board. The electromagnetic interference shielding component provides functions of EMI shielding, lightning (current) discharging and fixture, which can simplify the structure, increase the discharging speed and time, and reduce the amount of disturbance of the large current instantaneous to the ground.
