Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in both industrial and consumer applications due to their high capacity and low cost. A conventional aluminum electrolytic capacitor contains two aluminum foils which are separated by a thin layer of insulating film, such as electrolytic paper or plastic. The anode of the capacitor is connected to one of the aluminum foils and the cathode is attached to the other foil via an electrolyte solution. A voltage applied between the terminals of the capacitor causes electrical charging to occur, resulting in electrical current flowing in the circuit, and this current is stored as an electrical charge in the capacitor.An aluminum electrolytic capacitor has two main components: an electrolyte solution and the capacitive element made of two aluminum foils and insulating material. The electrolyte solution provides the necessary conditions for the charging of the capacitor and contains small amounts of acids, salts, and organic substances. The two aluminum foils are separated by an insulating material, and this material helps prevent internal shorting of the capacitor. The insulating material also has an important role in promoting the dielectric strength of the device.The UVR2A3R3MDD1TA is an aluminum electrolytic capacitor from KEMET.
