Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as aluminum electrolytic capacitor, is a type of capacitor consisting of two aluminum foils with layers of oxidation applied to them. It uses electrons from the electrolyte to build up electrical charge on one of the plates, and it also has a dielectric material around the electrolyte. It is ideal for applications that require a low equivalent series resistance (ESR). The common aluminum electrolytic capacitor size codes that are used are 200BXC10MEFC8X11.5.

Application Field

Aluminum electrolytic capacitors are widely used in electronic applications. They are commonly used for power supplies, signal coupling, DC-to-DC converters, AC motor control, filters, and snubbers in power supplies. They are ideal for high-frequency applications because their ESR is low and their reactance is comparatively high. Furthermore, they can be found in more complex electronic designs, such as waveform generators, digital systems, power converters, and AC/DC power supplies. They are also widely used as energy storage devices in power plants and electric equipment.

In addition, aluminum electrolytic capacitors can be seen in the military industry. They are used in military communications and navigational equipment, such as satellite antennas, missiles, and secure communication systems. They provide the dynamic power needed to power the systems, and their low ESR makes them ideal for these military applications.

Working Principle

The aluminum electrolytic capacitor has two components: a dielectric, typically made of aluminum oxide, and an electrolyte, usually a mixture of sulfuric acid and water. The electrodes are made up of two aluminum foils, one of which is coated with an oxide layer. This oxide layer acts as an insulating layer and prevents electrons from escaping to the other side.

When the capacitor is connected to an AC power source, the alternating current will pass through the capacitor, moving electrons from the positive to the negative side. When the current flow is stopped, the negative electrode is left with a positive charge and the positive electrode is left with a negative charge. This creates an electric potential difference between the two electrodes, allowing electric charge to be stored in the capacitor.

The size of an aluminum electrolytic capacitor, denoted by 200BXC10MEFC8X11.5, represents the volume of the capacitor and its electrical parameters. The voltage rating represents the maximum voltage that can be applied to the capacitor. The capacitance is the amount of electricity that can be stored and is measured in Farads. The size also determines the effective series resistance, which determines the amount of energy that can be dissipated by the capacitor.

The aluminum electrolytic capacitor is a reliable and cost-effective way to store and deliver energy in a wide range of applications. It offers low ESR and high capacitance levels, making it an ideal choice for power-hungry applications. Its size and electrical parameters make it an ideal choice in applications such as power supplies, signal coupling, DC-to-DC converters, and AC motor control.
