Aluminum Electrolytic Capacitors: UVZ2A220MEH Application Field and Working Principle

Aluminum electrolytic capacitors are mainly used to store electrical energy and filter out high frequency noise. Among all types of electrolytic capacitors, the aluminum electrolytic capacitor is the most widely used and developed one. The capacitor with the part number of UVZ2A220MEH is adopted by many electronic and electrical products due to its excellent properties and specifications.

The main application fields of the capacitor UVZ2A220MEH includes DC-link, motor drive, LED lighting, anti-interference, and power quality improvements, etc. It is specifically designed to offer constant voltage filtering on a DC input to stabilize the output. It is able to reduce the ripple current effectively. In addition, it can be used in drives and instrumentation for motor speed controls, allowing for providing a starting torque and precise speed control.

As a kind of polarized capacitors, the aluminum electrolytic capacitor UVZ2A220MEH consists of two or three pins. The positive pin represents the anode and the others are the cathode. It has one roll of aluminum foil as anode, while the cathode is constituted of a high conductivity material-either an oxide of aluminum or a manganese oxide. The two materials are separated by a thin film. The electrolyte used is a solution of ethylene glycol and ammonium borate, which works as a conducting medium for the ions to move in.

The principle of aluminum electrolytic capacitors is based on the high dielectric constant and electrical conduction of the aluminum oxide film. The oxide film is formed reversely on the cathode. By applying voltage, a thin electrostatic field is induced on aluminum oxide, making it possible to separate the charges and store electricity. The manufacturing process also involves forming and fixing terminals on the capacitor. During the process, heat insulation is a critical factor.

The aluminum electrolytic capacitor UVZ2A220MEH offers exceptional filter capability for large current resonance, low ESR, low impedance and high ripple current. With its capacitance up to 220μF, it is able to capture high frequency noises, yielding optimal performance. In a nutshell, the UVZ2A220MEH aluminum electrolytic capacitor is extremely efficient in filtering out noises of DC input source and delicate devices.
