    摘要： A multi-layer capacitor achieves significant reduction in equivalent series inductance (ESL) and includes first inner electrodes and second inner electrodes opposing each other, first feed-through conductors and second feed-through conductors, and first outer terminal electrodes and second outer terminal electrodes. The first feed-through conductors electrically connect the first inner electrodes and the first outer terminal electrodes, and the second feed-through conductors electrically connect the second inner electrodes and the second outer terminal electrodes. The first and second feed-through conductors are arranged such that the feed-through conductors mutually cancel magnetic fields induced by current flowing through the first and second inner electrodes. Furthermore, when an alignment pitch of the first and second feed-through conductors is indicated by P and the total number of the first and second feed-through conductors is indicated by N, an arrangement is set such that a ratio of P/N is about 0.085 mm or lower.

    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 multi-layer capacitor includes first and second side-surface terminal electrodes alternately arranged on four side surfaces of a capacitor body. First and second major-surface terminal electrodes are arranged on a major surface of the capacitor body. First and second internal electrodes which are opposed to each other within the capacitor body are respectively electrically connected at ends thereof to the first and second side-surface terminal electrodes, and are also respectively electrically connected to the first and second major-surface terminal electrodes through via hole conductors. With this arrangement, the directions of the currents flowing within the multi-layer capacitor are diversified, and the lengths of current-carrying paths are shortened so as to achieve a very low ESL value.
