Title:
MULTILAYERED COMMON MODE FILTER
Document Type and Number:
WIPO Patent Application WO/2024/071719
Kind Code:
A1
Abstract:
Disclosed is a multilayered common mode filter having first and second capacitance layers arranged on the top and bottom surfaces, respectively, of an electrode layer provided with a plurality of coil patterns that form two channels. The disclosed multilayered common mode filter comprises first and second capacitance layers, symmetric with an electrode layer interposed therebetween, wherein the first and second capacitance layers are in the form of ground patterns and capacitor patterns stacked in alternation, and, along with a pole formed by the coil patterns, an additional pole is formed by the capacitance layers and coil patterns to exhibit wideband characteristics.
