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.

This disclosure is directed to an improved LC filter which includes a cylindrical ferrite member of a semi-conductor material formed with an inner bore which axially extends through its central portion, and having its grain boundary and/or at least its outer peripheral surface formed into an insulating layer, an electrode provided at least on the outer peripheral surface of the cylindrical ferrite member, and a through-conductor inserted into the inner bore of the cylindrical ferrite member.

A high voltage variable resistor section (8) for deriving the focusing voltage and screen is attached to an open portion formed on one surface of a first case (47) which receives primary and secondary windings (2, 3) included in a flyback transformer section (1). An insulating substrate (16) on which resistor elements (9-13) included in the high voltage variable resistor section are formed in housed in a second case (15). An opening is formed in one surface of the second insulating cases (15). With this opening communicating with the opening in the first insulating case, the two insulating cases are integrated. These insulating case define insulating case means, in which a high voltage capacitor (14) for compensating cathode ray tube capacity is housed. The high voltage capacitor is disposed between the secondary winding (3) and the resistor elements (9-13) in such a manner that the surfaces of the electrodes (38, 39) of the high voltage capacitor are opposed to the secondary winding (3) and the resistor elements (9-13). This arrangement prevents unnecessary radiation components due to ringing noise induced in the secondary winding from being transferred to the resistor elements and superposed on the focusing voltage.
