Title:
NOISE FILTER
Document Type and Number:
Japanese Patent JP2020129720
Kind Code:
A
Abstract:
To provide a versatile noise filter reducing equivalent series inductance of a capacitor, and parasitic inductance of wiring for connecting the capacitor.SOLUTION: A noise filter includes a first conductive wire having an input side conductive wire extending between an input end and an output end, and extending between the input end and a branch part, and an output side conductive wire extending between the output end and the branch part, a second conductive wire connected with the branch part of the first conductive wire and into which a capacitor is inserted, and a magnetic substance surrounding at least a part of one of the input side conductive wire or the output side conductive wire, and at least a part of the second conductive wire. The magnetic substance is configured to reduce the equivalent series inductance of the capacitor and the parasitic inductance of the second conductive wire by intersecting magnetic flux, generated from the input side conductive wire or the output side conductive wire, with magnetic flux generated from the capacitor and the second conductive wire, so as to be cancelled.SELECTED DRAWING: Figure 3
