  • Publication number: 20180019591
    Abstract: Disclosed is a multi-layer electric shock protection EMI filter device and a manufacturing method thereof. The multi-layer electric shock protection EMI filter device is formed by cofiring a laminated ceramic dielectric material layer, and includes: a lower capacitor, an electric shock protection device, and a upper capacitor; wherein the electric shock protection device is disposed between the lower capacitor and the upper capacitor, and isolated from the lower capacitor and the upper capacitor by a ceramic dielectric material layer, and a tripping layer is provided between two wires in the electric shock protection device, and formed by a mix of SiC and glass. After the main body is stacked and a low temperature cofire process is performed, the tripping layer becomes a compound structure of a SiC body and an air gap. Accordingly, an integrated electric shock protection EMI filter device can be manufactured to prevent electromagnetic interference, filter, and electric shock.
