Combined varistor and LC filter device

A combined varistor and LC filter device, comprising:

• a body configured to have a rectangular hexahedron shape, and mainly composed of zinc oxide, the zinc oxide functioning as an insulator at voltages below a predetermined level and resistance of the zinc oxide decreasing rapidly at voltages above a predetermined level;
• outer ground electrodes formed on opposite side surfaces and having relatively short lengths among outer surfaces of the body, and connected to a ground;
• input and output electrodes formed on opposite side surfaces and having relatively long lengths among the outer surfaces of the body to input and output signals;
• a plurality of inductance patterns disposed to be parallel to predetermined planes inside the body, and configured to have predetermined lengths, respective ends of the inductance patterns being connected to the input and output electrodes;
• two or more inner ground patterns formed parallel to each other above and below predetermined planes under the plurality of inductance patterns and connected to the outer ground electrodes;
• and
• a plurality of capacitance patterns formed in a predetermined planes between the inner ground patterns to be positioned parallel to each other, and selectively connected to the input and output electrodes;
• wherein the combined varistor and LC filter device is formed in a multiple terminal array structure.
