Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are the most commonly used capacitors for energy storage and energy delivery. They consist of an aluminum foil with an anode layer and a plastic film as a dielectric insulation. The anode layer is an electrolyte layer consisting of a dielectric material and an electrolyte. The dielectric material is usually a polymer such as polyethylene, polypropylene, or polystyrene. The electrolyte is usually an alkaline solution such as potassium hydroxide, sodium hydroxide, or ammonium hydroxide.

381LQ152M200K042 Application Field and Working Principle

The 381LQ152M200K042 aluminum electrolytic capacitor is a type of aluminum electrolytic capacitor designed for use in power applications. It is designed for applications requiring high power density and high reliability with voltage ratings up to 200VDC. The capacitor has an extended life of up to 2000 hours operating temperature range of -55°C to +85°C. This makes it ideal for use in high-temperature, aggressive, and demanding environments.The 381LQ152M200K042 aluminum electrolytic capacitor is designed with a series of three aluminum foil layers. A positive foil layer, a dielectric layer, and a negative foil layer are sandwiched together and sealed inside a plastic or metal package. The dielectric layer is usually made of a plastic film, such as polypropylene or polyester, and is used to provide an insulation barrier between the two metal foil layers.An electric current applied to the capacitor causes an electric charge to be stored between the two metal electrodes. The amount of charge stored is determined by the size of the capacitor and the voltage applied. The charge is stored in the electric field established by the electric current and the dielectric between the two metal electrodes. This electric field generates forces that induce a mechanical displacement of the positive and negative foil layers, resulting in an increase or decrease in capacitance.The 381LQ152M200K042 aluminum electrolytic capacitor is designed for high-power applications, and has a maximum ripple current rating of 150A. Its capacitance is typically 160μF at 200VDC. With an operating temperature range of -55°C to +85°C, the 381LQ152M200K042 is highly reliable, even in extreme temperature environments. It has a long life expectancy and is very reliable in high-temperature, aggressive, and demanding applications.
