Aluminum electrolytic capacitors are types of capacitors that are constructed by using an electrolyte, made of an organic solvent, as the dielectric. The aluminum electrodes of the capacitor are composed of two aluminum foil sheets, with each one having a thin oxide film of anodic aluminum oxide. This oxide film acts as a dielectric and insulator. The foil layers of the capacitor are spaced apart a short distance by the electrolyte, which allows the electric field of the capacitor to function properly. The aluminum electrolytic capacitor, in terms of its electronic properties, strongly depends on the characteristics of the oxide layer, which can be altered by either applying an external voltage or changing the concentration of the electrolyte.

The MAL213819221E3 is an aluminum electrolytic capacitor that has been specifically designed for applications in high-voltage power supplies. Its construction consists of two aluminum foil electrodes with an anodic aluminum oxide dielectric layer in between them. The foil electrodes are separated by the electrolyte, which is a solution of ethylene glycol and boric acid in propylene glycol. The capacitor is covered with a polypropylene sleeve. The capacitor can be easily mounted onto a printed circuit board. The metal end cap and the stainless steel screws are made of corrosion-resistant materials to ensure a long life and high reliability.

The MAL213819221E3 is designed for applications such as high-voltage spike suppression, surge power supplies, high frequency switching, and DC power supplies. It is also suitable for use in low ESR applications such as filter networks, resonance circuits, high speed amplifiers, and frequency converters. The capacitor is also suitable for applications where vibration resistance and reliability are important, such as aerospace and automotive applications. The MAL213819221E3 has an Insulation Resistance of >250MΩ and an overload current of 3A. It operates at a wide temperature range of -40 to +125°C.

The working principle of the MAL213819221E3 is based on the concept of capacitance, which is the ability of a capacitor to store an electric charge. In an aluminum electrolytic capacitor, charges accumulate on the two aluminum layers, separated by the electrolyte. This creates an electric field between the layers, which produces a potential difference. When an external voltage is applied to the capacitor, a current flows through the capacitor, which creates a change in the potential across the capacitor. The capacitance of an aluminum electrolytic capacitor increases as the applied voltage increases, enabling the capacitor to store more charge.

Overall, the MAL213819221E3 aluminum electrolytic capacitor is a highly reliable, long-lasting component, suitable for use in high-voltage power supplies and other vibration-resistant applications. Its working principle and design features ensure that it is able to store and safely transfer large amounts of electric energy for long periods of time.
