Aluminum Electrolytic Capacitors

MLP473M7R5EB1C is a type of Aluminum Electrolytic Capacitor, and belongs to the MLP-E range which has been significant in the market for over 30 years. It is ideal for use in the most demanding applications in the telecommunications, consumer, data processing, computer, instrumentation, and medical markets.

Aluminum electrolytic capacitors are capacitors whose anode electrode that is made of a pure aluminum foil with an etched surface, and its oxide layer acts as the dielectric. Its structure also consists of a liquid or solid electrolyte that can react with the aluminum anode and serve as the electrical connection between the two electrodes.Therefore, aluminum electrolytic capacitors have very large capacitance values per size compared to other types of capacitors and also very high electrical resistant values.

The MLP473M7R5EB1C is a PCB-mounting capacitance that has a long life expectancy and high ripple current capability, with rated voltage ranges from 16 V to 450 V. It is mainly designed for applications such as power factor correction, switching mode power supplies, inverters, and automotive applications. The series is characterized with high efficiency, low equivalent series resistance (ESR), and long life expectancy.

Working Principle

When a voltage is applied to an aluminum electrolytic capacitor, current is created and a thin layer of aluminum oxide is formed on the surface of the aluminum. This oxide layer is the dielectric of the aluminum electrolytic capacitor. The more voltage is applied, the thicker the oxide layer becomes, thus increasing the electrical resistance of the capacitor. This is why aluminum electrolytic capacitors can withstand higher electrical current than other types of capacitors.

The MLP473M7R5EB1C capacitor is kept in operation by being subjected to an electric current. As the current passes through the capacitor, a build-up of ions starts to form between the anode and the cathode. These ions form an electric field, which creates a charge difference between the two electrodes, creating a potential energy stored in the capacitor. This energy is used to supply power to the capacitor when needed.

Application Field

The MLP473M7R5EB1C is mainly used for applications such as power factor correction, switching mode power supplies, inverters, and automotive applications. It is highly recommended for high voltage, high ripple current handling, and long life expectancy applications. It is also well-suited for applications where size and weight are limited, such as medical and communications equipment.

It is also used in motors and generators due to their high voltage withstanding capabilities and high power density. This type of capacitor is also used in memory modules, battery chargers, and other industrial applications as well.
