Capacitor element and capacitor device having the same

摘要

A capacitor forming unit according to one embodiment includes a dielectric plate with a plurality of through holes; a first conductor film formed on an upper surface of the dielectric plate; a first insulator film formed on the front end portion of the upper surface of the dielectric plate; a second conductor film formed on a lower surface of the dielectric plate; a second insulator film formed on the rear end portion of the lower surface of the dielectric plate; first electrode rods disposed in some of the through holes; and second electrode rods disposed in the remaining through holes where the first electrode rods are not disposed. The first electrodes are electrically connected to the first conductor film and electrically insulated from the second conductor film. The second electrode rods are electrically connected to the second conductor film and are electrically insulated from the first conductor film.

主权项

1. An individual capacitor forming unit comprising:
a dielectric plate having a plurality of through holes formed in the thickness direction; a first conductor film formed on a region of an upper surface of the dielectric plate other than a front end portion of the upper surface; a first insulator film formed on the front end portion of the upper surface of the dielectric plate; a second conductor film formed on a region of the lower surface other than a rear end portion of the dielectric plate; a second insulator film formed on the rear end portion of the lower surface of the dielectric plate; one or more first electrode rods disposed in some of the plurality of through holes of the dielectric plate, the first electrode rods being electrically connected to the first conductor film and electrically insulated from the second conductor film; and one or more second electrode rods disposed in the through holes of the dielectric plate in which the first electrode rod is not disposed, the second electrode rods being electrically connected to the second conductor film and electrically insulated from the first conductor film, wherein the first conductor film and the first insulator film form an upper outer surface of the individual capacitor forming unit, wherein the second conductor film and the second insulator film form a lower outer surface of the individual capacitor forming unit, and wherein either the upper outer surface or the lower outer surface, or both, of the individual capacitor forming unit is configured for direct contact with at least one outer surface of another adjacent individual capacitor forming unit to form a capacitor when electrically connected.
