Abstract
A capacitor (20A-E) formed as a roll of inner and outer electrode strips (21, 23) alternating with inner and outer dielectric strips (22, 24). Each of the dielectric strips (22, 24) is shorter than an inwardly adjacent one of the electrode strips (21, 23) at a radially outer end thereof (21 E, 23E). This exposes the radially outer end of each electrode strip on respectively different portions of an outer side surface (26, 28) of the capacitor. The exposed ends of the electrode strips may be arranged on opposite sides of the capacitor, such that stacking the capacitors interconnects them either in parallel, in series, or in combinations thereof in different embodiments.
