    摘要： Disclosed herein is a differential mode filter that includes first and second terminal electrodes provided on a first flange part of a core, and first and second wires wound around a winding core part of the core in an opposite direction to each other and connected respectively to the first and second terminal electrodes. The first and second wires cross each other on the winding core part to form a plurality of crossing portions that include first, second, and third crossing portions that are first, second, and third occurrences counting from the one end of the first and second wires, respectively. A first crossing angle between the first and second wires at the first crossing portion is larger than at least one of second and third crossing angles between the first and second wires at the second and third portions, respectively.

    摘要： A noise reducer is provided that ameliorates electromagnetic noise interference. More specifically, the noise reducer ameliorates electromagnetic noise interference for electronic equipment caused by noise superimposed on a conductor wire. The conductor wire includes a magnetic cylindrical core that penetrates a hollow hole, a winding coiled around the magnetic cylindrical core, and an impedance element connected to the winding. When a noise current is superimposed on the conductor wire that has been made to penetrate the magnetic cylindrical core, part of the noise current is electromagnetically induced from the conductor wire to the winding and flows to the winding. The noise current that flows to the winding is transformed into heat and consumed by the impedance element. As a result, the noise power that gives electromagnetic noise interference to the electronic devices can be reduced and the electromagnetic noise interference for the electronic devices ameliorated.

    摘要： An inductor device or filter such as an electromagnetic interference (EMI) filter which includes an inductor provides cancellation of parasitic capacitance of the inductor and extends high frequency performance of the inductor or filter by providing the inductor using split windings and including capacitors to couple signals corresponding to those which are passed by the equivalent parallel capacitance of the inductor to another split winding or an inductor in the ground return path. Cancellation of parasitic capacitance is provided for differential mode and common mode split windings where the split windings may be either inductively coupled or not. Forming the split windings as a bifilar winding to increase coupling coefficient further improves performance and allows cancellation (as distinct from parasitic capacitance reduction) and avoidance of resonance in circuits in which an inductor is not permitted in the ground return path.
