Abstract:
A multi-layer capacitor comprising:a capacitor body including a plurality of laminated dielectric layers; at least one pair of first inner electrodes and at least one pair of second inner electrodes, the pairs of first inner electrodes and second inner electrodes being mutually opposed via one of the plurality of the dielectric layers disposed inside of the capacitor body; first outer terminal electrodes and second outer terminal electrodes disposed on at least one main surface of the capacitor body, the main surface extending substantially parallel to the inner electrodes; a plurality of first feed-through conductors and a plurality of second feed-through conductors disposed inside of the capacitor body, the first feed-through conductors passing through specified dielectric layers of the plurality of the dielectric layers to electrically connect the first inner electrodes and the first outer terminal electrodes such state that the first feed-through conductors are electrically insulated from the second inner electrodes, and the second feed-through conductors passing through specified dielectric layers of the plurality of the dielectric layers to electrically connect the second inner electrodes and the second outer terminal electrodes in such a state that the second feed-through conductors are electrically insulated from the first inner electrodes, the first and second feed-through conductors being arranged such that the first and second feed-through conductors mutually cancel magnetic fields induced by current flowing through the inner electrodes; and first peripheral feed-through conductors included in the first feed-through conductors and second peripheral feed-through conductors included in the second feed-through conductors, the first peripheral feed-through conductors being connected to the first inner electrodes at the peripheries of the first inner electrodes, and the second peripheral feed-through conductors being connected to the second inner electrodes at the peripheries of the second inner electrodes.
