COMMON MODE FILTER AND METHOD OF MANUFACTURING THE SAME

摘要

The present invention relates to a common mode filter and a method of manufacturing the same. In order to implement a common mode filter with low shrinkage, high substrate sintered density, and high strength, the present invention provides a common mode filter including: a lower substrate; an insulating layer having a conductor pattern inside and provided on the lower substrate; an upper substrate provided on the insulating layer; and a ferrite core made of ferrite and provided in the center of the insulating layer, the lower substrate, and the upper substrate by penetrating the insulating layer, the lower substrate, and the upper substrate, and a method of manufacturing the same.

1. A method of manufacturing a common mode filter comprising:
preparing a lower substrate, an upper substrate, and an insulating layer having a conductor pattern inside; sequentially laminating the lower substrate, the upper surface, and the insulating layer from the bottom; forming a hole penetrating the insulating layer and the lower substrate or the upper substrate; and forming a ferrite core made of ferrite in the hole.
