Aluminum Electrolytic Capacitors: MLP842M035EA0AIntroductionAn aluminum electrolytic capacitor is a type of capacitor which uses an electrolyte in order to store electrical charge. It is composed of two thin aluminum foils, which are separated by a paper impregnated with a liquid electrolyte. It has a large capacitance, high ripple current and high voltage range. It also has a long life-span, usually between 2000 and 15000 hours.Application FieldMLP842M035EA0A aluminum electrolytic capacitors are used in a wide variety of applications, ranging from consumer electronics, signal processing, and communications equipment applications, to automotive power systems.In consumer electronics, they are used to reduce electrical noise and prevent high frequency oscillations. They are also used in the power supply of LCD and PDP TVs, and other consumer electronics.In signal processing, they are used as DC blocking capacitors, filtering capacitors, and also as coupling capacitors. They are also used in local oscillators and other radio frequency circuits.In communications equipment applications, they are used to filter out noise, and as feedback capacitors to improve signal reception. In automotive power systems, they are mainly used in starter motors, fuel injectors, and other electrical systems.Working PrincipleAluminum electrolytic capacitors operate by storing electrical charge in a liquid electrolyte between the two aluminum plates. The plates consist of a porous layer of aluminum oxide which acts as an insulator. When a voltage is applied across the plates, the electrolyte molecules are attracted to the plates, forming a dielectric layer between them. The larger the applied voltage, the stronger the attraction, thus increasing the capacitance of the capacitor.The electrolyte in an aluminum electrolytic capacitor plays a very important role in its performance. It helps to not only increase the capacitance, but also reduce the leakage current and increase the life-span of the capacitor.ConclusionMLP842M035EA0A aluminum electrolytic capacitors are widely used in a variety of applications, due to their high capacitance, high voltage range, and long life-span. They are used to reduce electrical noise and to improve signal reception. They also find use in starter systems, fuel injectors, and other automotive power systems. The working principle of the aluminum electrolytic capacitor is based on the attraction of the electrolyte molecules to the plates formed by the porous layer of aluminum oxide, which increases the capacitance of the capacitor.
