Aluminum electrolytic capacitors are widely used in most electronic circuits due to their high capacitance per unit volume, excellent temperature characteristics and low manufacturing cost. The MALREKB00AA210JM0K aluminum electrolytic capacitor is a miniature, high-performance polarized electrical component that is used in a variety of applications. It has a small form factor, low ESR (equivalent series resistance) and higher ripple current capacity.

Aplication Field

The MALREKB00AA210JM0K is widely used in a variety of electronic projects as the frequency range is quite wide. This type of capacitor is ideal for use in consumer electronics and other applications that require low ESR values and a miniature size. It is primarily used in power supplies, as it can help to stabilise the output voltage and current. It is also used in DC-DC converters as a filter capacitor and can provide important stabilisation benefits by reducing output ripple and noise. In radio frequency and audio-frequency applications, this type of capacitor can provide high-frequency filtering and slight resonance tuning. This capacitor can also be used in timing circuits, such as tuned circuits, filters, and amplifiers.

Working Principle

The MALREKB00AA210JM0K uses an electrolyte saturated with an ionic solution between two layers of aluminum foil. The electrolyte is typically an aqueous solution containing sulfuric acid or aluminum hydroxide. A layer of aluminum oxide film is formed on the foils, which serves as the dielectric for the capacitor. Through the relationship of Faraday’s law of electrolysis, the electrolyte charges the capacitor.

The capacitor has a positive plate made of aluminum foil, along with a negative plate made of foil, with the oxide film between them. A voltage is applied to the positive plate, causing the electrolyte to be oxidised and attracted to the foil. This creates an electric field between the electrodes, and the charge accumulates on the surface of the film. As the voltage increases, the electric field increases, and the dielectric becomes stronger. The charge on the surface of the film repels the ions from the electrolyte, causing them to move outward and neutralise the electric field. This process eventually reached equilibrium and is maintained when a constant voltage is applied.

In the MALREKB00AA210JM0K, the dielectric oxide film is quite thin, yet strong enough to store a significant amount of energy. The capacitor is sealed at the factory and the electrolyte is relatively non-volatile, which makes the capacitor suitable for use in exposed environments. Thanks to its small size, the MALREKB00AA210JM0K can be installed in tight spaces on a printed circuit board.

Overall, the MALREKB00AA210JM0K aluminum electrolytic capacitor is a highly efficient, small-sized polarized electrical component that is suitable for many different applications. It is capable of handling severe temperature variations without suffering any performance issues, and its electrolyte is sealed and relatively non-volatile. This makes it suitable for use in exposed environments. Its miniaturized form factor also makes it ideal for tight spaces.
