Abstract
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.
