Large Can Aluminium Electrolytic Capacitors - Screw Terminal | Kemet

Electrolytic capacitors consist of aluminum foil which is first etched to increase its surface area. Separate, carefully designed etching techniques are used for the anode and cathode foils. A layer of aluminum oxide, an excellent dielectric, is formed on the surface of the etched anode foil before the foils are wound together between special separator papers. At the same time, tabs are welded to the foils to form the connections. The wound assembly is impregnated with a liquid electrolyte. This electrolyte is a precisionmade compound which fully impregnates the etched foil, providing a low ESR conductive path to the cathode foil with stable electrical and chemical properties. KEMET crafts its own electrolytes to match the etched foil characteristics and desired final properties. The assembly is packaged in such a way as to provide excellent vibration resistance and low thermal resistance.
