  • Patent number: 7835135
    Abstract: There is a provided a magnetic and dielectric composite electronic device, comprising: a first region with a plurality of magnetic material sheets being layered; a second region with a plurality of dielectric material sheets being layered; and a third region as a middle layer interposed between the first region and the second region, including a Zn—Ti based material to prevent diffusion of the materials during co-firing of the first region and the second region, and the first region, the second region and the third region are integrally formed in a single body. In accordance with the present invention, the low pass filter including the function of the varistor is realized to obtain the EMI function and the ESD control effect.
