Aluminum electrolytic capacitors (Al electrolytic capacitors) are widely used internationally in the design of electronic equipment and circuits and comprise a substantial portion of the electric components in these designs. The MAL219877181E3 is an aluminum electrolytic capacitor specifically designed to perform a variety of functions and is used in applications such as high current filters, power supplies, motors, converters, and rectifiers. It is also used in circuit boards for controlling voltage and current.

Aluminum electrolytic capacitors are polar devices, meaning that only one polarity can be connected at a time. This is important in many circuits since incorrect polarity connection may cause the capacitor to become damaged or even fail. The internal construction of this type of capacitor comprises two aluminum foils, separated by a layer of oxide. The metal oxide layer is formed through the electrolyte anodization of the aluminum foil. Electrical charge is stored on the aluminum foil by the application of a voltage, and this charge is the basis of the capacitor’s capacitance.

Working Principle

The working principle of the MAL219877181E3 is the same as that of other aluminum electrolytic capacitors. When a voltage is applied to its anode and cathode, the metal oxide layer is polarized and an electric field is produced between the two conductors. This electric field accumulates electrical charge on the Al foil layers, creating a dielectric between the two, that stores electrical energy. When the applied voltage is removed, the previously created electric field is removed, and the charges stored on the two layers remain. Thus, in the absence of an external voltage, the stored charges remain on the capacitor.

In essence, the metal oxide layer acts as an insulator, keeping the two conductors of the capacitor separated until a voltage is applied to it. When a voltage is applied to the two conductors, the oxide layer breaks down and the aluminum layers become conductive. The capacitor is now able to store electrical energy in the form of charge. The amount of charge that can be stored in the capacitor is determined by the area of the aluminum layer, the thickness of the oxide layer, and the applied voltage.

Application Field

Aluminum electrolytic capacitors are used in applications where the amount of energy to be stored must be regulated or adjusted. In particular, they are often used in circuits that need to perform timing functions, such as motor controllers or regulators. They are also used to filter out electrical noise caused by the alternating current in motor controllers and power supplies. They can also be used to store charge in circuits that require large current draws, such as in solar panels, battery chargers, and boost converters.

The MAL219877181E3 can also be used in applications that require high insulation and excellent temperature and voltage stability. It is ideal for high current filters in AC to DC converters, relays, and power supplies. It is also suitable for use in circuits that require high voltage regulation, such as automotive applications.

The MAL219877181E3 aluminum electrolytic capacitor is a reliable and efficient electrical component that is ideal for a variety of applications. It has a high current capability, excellent temperature and voltage stability, and can store large amounts of charge for a long time. Its polarized design ensures that the capacitor will not be damaged by incorrect polarity connections.
