Multilayer capacitor and usage method therefor

摘要

A multilayer capacitor includes a multilayer body including a dielectric layer, first through third inner electrodes, and first and second capacitor sections, and first through third outer electrodes on surfaces of the multilayer body. The first capacitor section is electrically connected between the first and second outer electrodes. The second capacitor section is electrically connected between the second and third outer electrodes. The first, second, and third inner electrodes are connected to the first, second, and third outer electrodes, respectively. The first and third inner electrodes oppose each other with the dielectric layer therebetween, thus defining the first capacitor section. The second and third inner electrodes oppose each other with the dielectric layer therebetween, thus defining the second capacitor section.

1. A multilayer capacitor comprising:
a multilayer body including a dielectric layer and first, second and third inner electrodes and including first and second capacitor sections, the first capacitor section being connected to a voltage smoothing circuit; and a plurality of outer electrodes disposed on surfaces of the multilayer body and including first, second, and third outer electrodes; wherein the first capacitor section is electrically connected between the first and third outer electrodes; the second capacitor section, which decreases a potential difference applied to the first capacitor section, is electrically connected between the second and third outer electrodes; the first, second, and third inner electrodes in the multilayer body are connected to the first, second, and third outer electrodes, respectively; the first and third inner electrodes oppose each other with the dielectric layer therebetween so as to define the first capacitor section; the second and third inner electrodes oppose each other with the dielectric layer therebetween so as to define the second capacitor section; the first inner electrode has a greater electrode area than an electrode area of the second inner electrode; an area by which the first and third inner electrodes oppose each other is different from an area by which the second and third inner electrodes oppose each other; the first and second capacitor sections are disposed in a stacking direction of the multilayer body; and in the stacking direction, at least one first capacitor section is positioned between a pair of the second capacitor sections, and at least one second capacitor section is positioned between a pair of the first capacitor sections.
