Document Type and Number:
WIPO Patent Application WO/2020/060152
Kind Code:
A1
Abstract:
The present invention relates to a common mode filter for a vehicle, which is mounted inside a vehicle, and comprises a filter part, a first external terminal, and a second external terminal, wherein the filter part comprises a dielectric layer made of a plurality of dielectric sheets, the dielectric layer comprises a plurality of coil patterns each arranged on a different layer, a portion of the plurality of coil patterns is connected in parallel to form a first channel, and the other portion of the plurality of coil patterns is connected in parallel to form a second channel. Therefore, the present invention can improve eye pattern signal quality by reducing resistance, while minimizing the reduction in common mode impedance due to the resistance reduction.
