Introduction to Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a type of capacitor that utilizes an electrolyte to achieve a larger capacitance than other types. It is composed of two metallic plates—the anode and the cathode, submerged in the electrolyte. A lightly charged layer of aluminum oxide is formed on the surface of the anode, which serves as a dielectric layer to store energy.

ERLA201LIN152KR55M Application field and Working Principle

ERLA201LIN152KR55M is aluminum electrolytic capacitor from Samsung Electronics. It has a maximum capacitance of 180μF and a rated voltage of 25V. It has a maximum operating temperature of +105°C with a life span of more than 5000 hours. It is widely used in the industrial field, and is often employed in power supplies, filtering circuits, and DC-DC converters.

The working principle of the ERLA201LIN152KR55M is based on the reversible electrochemical reactions that occur in electrolytic capacitors. Upon application of an electrical voltage, the oxygen and hydrogen ions that make up the electrolyte become transversely polarized and form an insulated layer of aluminum oxide. This formation of an insulated layer is what allows the ERLA201LIN152KR55M to store energy.

The ERLA201LIN152KR55M also utilizes a reversed polarity in order to reverse the process and discharge energy in an orderly fashion. This helps to regulate the current level of discharging and ensures the capacitor does not discharge without control.
