摘要： The present invention is to provide a monolithic capacitor for reducing an equivalent series inductance of a monolithic capacitor. The external terminal electrodes are respectively provided on four corners of the capacitor body. External terminal electrodes can also be provided on the side surfaces of the capacitor body. The first inner electrode is connected to two adjacent external corner terminal electrodes and preferably to the external side terminal electrode. The second inner electrode faces the first electrode through a dielectric layer and is connected to other two adjacent external corner terminal electrodes as well as to the external side terminal electrode. The current flowing through the inner electrodes is directed to a variety of directions, and since the current flow in the corner parts of the inner electrodes is smooth, the magnetic fluxes generated in association with the current are cancelled out, thereby reducing the equivalent series inductance.

摘要： A laminated chip-type LC filter for use as a noise filter is obtained by carrying out the following steps: dielectric layers are laminated on the top and bottom of a magnetic material layer, forming an inductor portion by providing conductive lines inside the magnetic material layer and forming capacitors by providing at least two layers of parallel internal electrodes inside both of the dielectric layers. External electrodes are provided at both ends of the inductor portion. Intermediate external electrodes are provided at both lateral sides in the middle part of the dielectric layers and the magnetic layer. The inductor portion is connected to the external electrodes. The internal electrodes are connected to the intermediate external electrodes and to the external electrodes, respectively. By making the intermediate external electrode the ground, the internal electrodes are grounded so that stray capacitance does not arise between the internal electrodes thus causing less deterioration of the insertion loss characteristic in the high-frequency area.
