Working Principle

The MAL214270479E3 capacitor is a non-polar capacitor. It is usually composed of two metal plates, an electrolyte, and a dielectric oxide film, which is formed by an electrolysis process. The metal plates can be aluminum or tantalum, and the most common metal plates are made of aluminum foil.

The metal plate is sandwiched between two insulating layers that are soaked in electrolyte and each are stacked one above the other. When voltage is applied, owing to the dielectric action of the dielectric oxide film, the electrolyte separates the two metal plates, forming a capacitor that stores electric charge.

Aluminum electrolytic capacitors have their own unique advantages compared with other electrolytic capacitors. They have a wide voltage range, high capacitance, good reliability and stability, and most importantly, They are cheap and easily obtainable.

Conclusion

The MAL214270479E3 is an aluminum electrolytic capacitor with wide applications in various electronic systems, such as power supply filtering decoupling, DC motor starters, audio, video, communication and other electronic circuits. Its working principle is based on the dielectric action of the dielectric oxide film that forms a capacitor between two metal plates.
