摘要:
Disclosed herein are a common mode noise chip filter and a method for manufacturing the same, the common mode noise chip filter including: a ferrite substrate; coil patterns formed on the ferrite substrate; and a ferrite-polymer complex layer formed on the result substrate having the coil patterns formed therein, wherein the ferrite-polymer complex layer has a multilayer structure, so that the ferrite-polymer complex layer filling an inner space of the substrate having inner coil patterns is formed to have the multilayer structure but not a single-layer structure, thereby lowering internal stress, and thus improving reliability of the common mode noise chip filter as a product.
