In summary, aluminum electrolytic capacitors deliver superior capacitance and energy densities when compared to film capacitors. They are ideal as power electronics bus capacitors and can be used in a variety of applications such as: power-supplies, bus capacitors for inverters, photo and strobe flashes, and welders. Cornell Dubilier produces several different large aluminum electrolytic capacitors including general purpose, snap-in, hi-ripple, and flatpack designs.
