Abstract
A capacitor having a housing defining a chamber, and having at least two internal alignment elements in the chamber. A plurality of capacitor layers, each having alignment holes formed therein to precisely fit the housing's alignment elements, is positioned within the chamber, with the alignment holes mating with the alignment elements. The housing may be electrically conductive and used to connect some capacitor elements, in which case the alignment elements include non conductive spacers that contact the alignment holes of the sheets. The housing may also include external index elements for precisely positioning the housing in registration with fixtures used for manufacturing processes requiring precise alignment.
