Aluminum Electrolytic Capacitors feature an anode constructed of aluminum foil with an etched surface. A cathode is formed by coating one or both sides of the aluminum foil with a catalytic material, typically manganese dioxide. The two electrodes are separated by a nonconductive electrolyte, typically a mixture of water and ethylene glycol that has been impregnated with a conductive element. Feedthroughs are formed by either using glass-encased thin-film carbon electrodes or by using an electroplated cathode. These feedthroughs, or leads, are necessary to allow current to flow through the capacitor. They are also typically used to connect the capacitor to external circuitry.

The TVA1180 Aluminum Electrolytic Capacitor, or TVA, is a high performance, high voltage aluminum electrolytic capacitor. It has an eight-layer construction, with three layers of aluminum foil, two layers of manganese dioxide and three layers of electrolyte paper. The capacitor has an operating temperature range of -55°C to 125°C and a capacitance range of 1uF to 4uF. The TVA has a maximum voltage rating of 1180VDC (Volts Direct Current) and a leakage current of 125mA (milli Amps).

The working principle of the TVA1180 aluminum electrolytic capacitor is based on Faraday’s Law of electrolysis. The principle states that the current caused by the reaction between the two electrochemical electrodes, the anode and cathode, is proportional to the difference
