Abstract
Abstract A capacitor network is provided for noise elimination on the input/output terminals of an electric computer or the like. A plurality of data electrodes are disposed on one surface of a dielectric substrate, and a common electrode is disposed opposite to the data electrodes on the other surface of the dielectric substrate. A pair of lead terminals are connected to each data electrode at both ends of the electrode, and at least one ground terminal is mounted to the common electrode, thereby forming a plurality of three-terminal capacitors in network.
