Abstract
A film capacitor includes metallization that is sectionalized, patterned and configured to provide interconnections on only one face of a rolled or stacked film capacitor.
Claims32
A film capacitor comprising metallization that is sectionalized, patterned and configured to provide interconnections on only one axial side/edge of a rolled or stacked film capacitor.
A method of making a film capacitor, the method comprising:
- patterning a first metalized film electrode group and a second metalized film electrode group to form a common dielectric structure;
- and
- rolling the common dielectric structure such that the first metalized film electrode group and the second metalized film electrode group together form a sectioned and patterned metalized film capacitor having interconnections on only one edge of a circular end of the capacitor.
A method of making a film capacitor, the method comprising:
- patterning a first metalized film electrode group and a second metalized electrode group to form a common dielectric structure;
- rolling the common dielectric structure such that together the first metalized film electrode group and the second metalized film electrode group form a roll of sectioned and patterned metalized film;
- slicing a desired number of sections from the roll of sectioned and patterned metalized film;
- and
- stacking the desired number of sections together to form a stacked metalized film capacitor having interconnections on only one edge of the stacked film capacitor.

A method of making a film capacitor, the method comprising:
- patterning at least one first metalized film electrode;
- patterning at least one second metalized film electrode;
- and
- stacking the at least one first metalized film electrode and the at least one second metalized film electrode such that together the at least one first metalized film electrode and the at least one second metalized film electrode form a stacked metalized film capacitor having interconnections on only one face of the stacked film capacitor.
