Film capacitor

摘要

A film capacitor includes a capacitor element and first and second external electrodes. The capacitor element includes a dielectric film, a first and a second electrode films facing each other across the dielectric film. The first electrode film includes electrode segments arranged in a matrix form, first fuses connecting the electrode segments adjacent to each other in a first direction, and second fuses connecting the electrode segments adjacent to each other in a second direction perpendicular to the first direction. The second fuses are arranged dispersedly in columns constituted by the electrode segments disposed in the second direction.

1. A film capacitor comprising:
a capacitor element having a first end and a second end arranged in a first direction, the capacitor element including
a dielectric film,a first electrode film disposed on the dielectric film, anda second electrode film facing the first electrode film across the dielectric film; a first external electrode disposed on the first end of the capacitor element and connected to the first electrode film; and a second external electrode disposed on the second end of the capacitor element and connected to the second electrode film, wherein the first electrode film includes:
a plurality of electrode segments separated by a plurality of first slits extending in the first direction and a plurality of second slits extending in a second direction perpendicular to the first direction, the plurality of electrode segments being arranged in a matrix form including a plurality of rows arranged in the first direction and a plurality of columns arranged in the second direction;a plurality of first fuses located at the plurality of second slits so as to connect electrode segments out of the plurality of electrode segments adjacent to each other in the first direction; anda plurality of second fuses located at the plurality of first slits so as to connect electrode segments out of the plurality of electrode segments adjacent to each other in the second direction, wherein at least one of the plurality of second fuses is located at each of the plurality of first slits, wherein the plurality of columns of the electrode segments consist of a farthest column farthest from the first external electrode among the plurality of columns of the electrode segments and one or more other columns other than the farthest column, wherein, in each of the one or more other columns, at least one electrode segment of two electrode segments out of the plurality of electrode segments adjacent to a certain one of the electrode segments in the second direction is electrically disconnected from the certain one of the electrode segments in the second direction, and wherein, in each of the one or more other columns, two electrode segments out of the plurality of electrode segments adjacent to each other in the second direction are electrically connected to each other via one of the plurality of second fuses.
