Title:
NOISE FILTER
Document Type and Number:
WIPO Patent Application WO/2019/220626
Kind Code:
A1
Abstract:
A noise filter (1) comprising two line capacitors, namely a first capacitor (16) and a second capacitor (17). By making the currents that flow through the first capacitor (16) and the second capacitor (17) flow in opposite directions and, at the same time, making the currents that flow through a first connection wiring (12) and a second connection wiring (15) flow in parallel and in the same direction, the connection wiring and the line capacitors are magnetically bonded, the residual inductance of the line capacitors is reduced, and the attenuation characteristics for normal mode noise are further improved.
