COMMON MODE FILTER AND CORE THEREOF

摘要

A common mode filter, comprising a winding core, and said winding core further includes a U-type heave portion, said U-type heave portion divides said winding core into a first winding portion, a second winding portion and a cross winding portion; the first winding wires, are wound on said first winding portion, said cross winding portion and said second winding portion in sequence; and the second winding wires, are wound on said first winding portion, said cross winding portion and said second winding portion in sequence. As a result, the common mode filter not only can reduce the effects of the existence capacitors of in high-frequency layers and the inherent functionality of parasitic capacitors in common mode filters with higher frequency characteristics, but also the overall structure is simple, fast assembly and easy operation.

1. A common mode filter, comprising:
a first flange, includes a first heave portion and a second heave portion; a second flange, includes a third heave portion and a fourth heave portion; a winding core, said first flange and said second flange are configured at the ends of said winding core, and said winding core further includes a U-type heave portion, said U-type heave portion divides said winding core into a first winding portion, a second winding portion and a cross winding portion; a first winding wires, are wound on said first winding portion, said cross winding portion and said second winding portion in sequence; and a second winding wires, are wound on said first winding portion, said cross winding portion and said second winding portion in sequence; wherein, numbers of turns of said first winding wires and said second winding wires provided on said cross winding portion are less than 1.
