Aluminum Electrolytic Capacitors: 30D158M050GK2A application field and working principle

Aluminum electrolytic capacitors are classics electrochemical capacitor composed of two aluminum foils and coated polyester film as the electrodes, rolled up into a cylindrical shape with a non-solid electrolyte. They are often used as decoupling filters, interconnection capacitors, and non-polarized start capacitors in AC circuits. The 30D158M050GK2A is a part of the aluminum electrolytic capacitors designed for specific uses.

Application Field of 30D158M050GK2A Capacitor

30D158M050GK2A capacitor is mainly used in AC circuits, such as television and computer power supplies, switching power supply rectification and filtering, high-frequency inverter driving, solar and wind energy systems, and so on. It has the advantages such as low equivalent series resistance, high heat resistance, high ripple current capability and long life.

Working Principle of 30D158M050GK2A Capacitor

30D158M050GK2A capacitor works in the same basic way as other aluminum electrolytic capacitors, using an electrolyte to create an electric current between the two plates. The aluminum foil is adopted as the anode while the polyester film coated with the anode oxide film is adopted as the cathode. When the applied voltage exceeds the film breakdown voltage, an electric current flows between two electrodes. The thin oxide film of aluminum foil serves as the capacitive dielectric layer and produces capacitive effect between the two plates.

The electrolyte consists of an aqueous solution of an acid or base, which can help to break down the voltage and increase the electric current within the plate. The current flow creates a reversible redox reaction at the anode and cathode, which can produce a large amount of free electrons, resulting in an increase of capacitance.

The 30D158M050GK2A capacitor is characterized by its high capacitance and superior performance in AC circuit applications. It is especially suitable for those applications that requires high capacitance, low equivalent series resistance, and wide temperature-range operation. It is also more stable in the face of temperature than other aluminum electrolytic capacitors.
