Aluminum Electrolytic Capacitors

The MAL203851222E3 is a type of aluminum electrolytic capacitor. An aluminum electrolytic capacitor works by storing electric charge and energy by acting as an interface between two objects such as a preamp and amplifier, or a signal and an oscillator. Such capacitors also serve as filters going between the power and ground in an electronic system.

Application Field

Aluminum electrolytic capacitors have a wide range of applications, including in computer motherboards, LCD and LED monitors, gaming systems, and other consumer electronics. These capacitors can also be used for filtering power and audio signals, motor controllers, alternators, and voltage regulators. MAL203851222E3 capacitors are especially useful where high voltage, high capacitance, long life, and/or high ripple current capacity are required.

Working Principle

Aluminum electrolytic capacitors work by having two aluminum foil electrodes, which are separated by an oxide film and an electrolyte. When a voltage is applied to the positive foil, the current is inserted into the negative foil via the electrolyte, forming an electric charge. The electrolyte can be formed from a variety of materials, including some corrosive materials such as sulfuric acid. The dielectric layer is usually made from a plastic film or a sintered aluminum oxide layer, depending on the capacitance and voltage ratings of the capacitor. This dielectric layer can also be formed from a tantalum or manganese electrolyte.

When the capacitor is not charged, the electrical field is uniform, and no current flows through the electrolyte. However, when the voltage is applied, the electrons flow and accumulate in the negative foil, creating an electric field. This electric field, in turn, causes a current to flow between the two foils. This current is responsible for charging and discharging the capacitor. The result is a capacitor that can store a large amount of energy.
