Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as wet electrolytic, are one of the most common types of capacitors available. These capacitors use an electrolyte-soaked film of aluminum oxide that is between two electrodes to achieve higher capacitance for the same size. Because of this, aluminum electrolytic capacitors are widely used in a variety of applications.The most commonly used aluminum electrolytic capacitors are the ESMH800VSN822MR50S series. This series of aluminum electrolytic capacitors has very high capacitance, with a capacitance range of 4.7μF ~ 3300μF. It is also offered in a wide range of voltage ratings up to 800 volts and can operate at high temperatures of up to 125°C. The ESMH800VSN822MR50S capacitors also have a low equivalent series resistance (ESR) and long lifetime of 3,000 to 5,000 hours, even at the highest operating temperatures.The main application for these aluminum electrolytic capacitors is to provide a power source for electronic devices, where high capacitance in relation to size is needed. Common applications include motor supplies, timing circuits, coupling and decoupling circuits, and power supply filtering. This series of aluminum electrolytic capacitors is also ideal for applications such as computers, appliances, and audio equipment.The working principle behind the ESMH800VSN822MR50S series of aluminum electrolytic capacitors is based on a process known as “electro-dialysis”. This process requires the use of a dielectric material that is exposed to electrolyte and electrodes. This dielectric material is usually an alumina film which is electrolyte-soaked by immersing the capacitor in a solution of potassium hydroxide and aluminum oxide.The electrolyte used in the aluminum electrolytic capacitors is mainly composed of potassium hydroxide, and it forms a thin layer of oxide around the electrodes of the capacitor. This oxide layer acts as a dielectric, allowing electricity to flow between the two electrodes. As voltage is applied to the capacitor, ions from the electrolyte move towards the positive and negative poles, forming electric charges of both signs in the electrolytic layer.These charges create an electrical field, storing energy and allowing electricity to flow between the two electrodes. The energy is stored until the capacitor is discharged, at which point it needs to be recharged with a new supply of electrolyte.The ESMH800VSN822MR50S series of aluminum electrolytic capacitors can be used in a variety of circuits where a large amount of energy needs to be stored quickly. The combination of high capacitance and long lifetime makes them a popular choice for many applications.
