Thin film type common mode noise filter and fabrication method of the same |
摘要 |
A thin film type common mode noise filter and its fabrication method are disclosed. There are several electric insulation layers, coil lead layers and main coil layers are formed on an insulation substrate by means of processes of Lithography, Physical Vapor Deposition, etching or other chemical process. After that the structure is covered with an electric insulation gluing layer and a magnetic material layer so as to form a thin film type common mode noise filter with a low production cost but an improved filtering characteristic of the common mode noise.
