Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as an electrochemical capacitor, is an electronic component composed of two aluminum foil electrodes with an electrolyte separating the plates. The aluminum electrolytic capacitor was invented by the German physicist Carl Hering in 1934. The aluminum electrolytic capacitor is one of the most widely used passive components in the electronics industry, playing a key role in many electronic circuits.

MAL213656561E3 application field and working principle

The MAL213656561E3 is a surface-mount aluminum electrolytic capacitor, available in a wide range of values. It has a high capacitance-voltage (CV) rating, making it ideal for applications that require a large amount of energy to be stored in a small amount of space. The MAL213656561E3 is well-suited for use in high-voltage and high-temperature circuits, as well as for fine-pitch applications. It is commonly used in high frequency power supplies, motor drives, surge suppression, and other industrial control applications.

The MAL213656561E3 operates on the same basic principle as all other aluminum electrolytic capacitors. The two aluminum foil electrodes are separated by an electrolyte, which is an ionized liquid or gel. When a voltage is applied across the electrodes, the positive ions present in the electrolyte are attracted to the negative foil and negative ions are attracted to the positive foil. This results in a build-up of charges on both foils, and a capacitance is established between them. As the voltage increases, the charges on the foils continue to build up, until they reach equilibrium with the applied voltage.

When the voltage is removed, the charges on the foils start to diminish, and the capacitance decreases. This process is known as charge leakage, and can reduce the capacitance of the capacitor over time. To prevent this, manufacturers often include a low-leakage electrolyte in their capacitors, which minimizes the amount of charge leakage. In addition, some capacitors include a feature known as “anti-mineral”, which helps to reduce the amount of charge leakage even further.

The MAL213656561E3 is an ideal component for many applications, due to its wide range of values, high CV rating, and low-leakage design. It can also be used in a variety of environments, including dry and damp locations. With its wide range of values and high capacitance-voltage rating, the MAL213656561E3 is an excellent choice for many high-frequency power supplies, motor drives, surge suppression, and other industrial control applications.
