SK220M050ST

Aluminum Electrolytic Capacitors are widely used in a variety of electronic circuits, from power supplies to amplifier stages. SK220M050ST is one of the most commonly used Aluminum Electrolytic Capacitors in the market. This capacitor is specially designed for industrial applications and to provide a reliable power supply for microprocessors.

SK220M050ST is a spherical fixed aluminum electrolytic capacitor with its working voltage being 50V. The capacitor has a capacitance of 220uF. It has a copper sleeve on one end and lead pins on both rectangular ends. The pins are diagonally concave and are easily insertable.

The application field of SK220M050ST mainly involves smoothing and filtering of power supplies, such as computer main board power supplies, flexible AC drive power supplies, etc. The capacitor can be used as the reservoir capacitor to reduce the ripple voltage and improve the stability of the power supply. It can also be used as a filter to block high-frequency noise entering the power supply, making the power supply more stable.

The working principle of SK220M050ST is based on the electrostatic capacitance between two conductors, which is a simple physical phenomenon. When an electrostatic field is created between two conductors, energy is stored in this electrostatic field. In an electrolytic capacitor, an electrolyte, usually a liquid with ions dissolved in it, functions as the dielectric medium. In this way electrons can be stored between the two metal plates and a capacitor can be formed.

The metal plates of electrolytic capacitors are normally made of aluminum as it is a capable conductor. Aluminum oxide easily forms on the electrolyte side and thus enhances the energy storage. In this way, a higher current can flow through the capacitor and therefore, it is suitable for usage in power supplies.

In conclusion, SK220M050ST is an Aluminum Electrolytic Capacitor specially designed for a variety of industrial applications, with its application fields mainly including smoothing and filtering of power supplies. The capacitor works on the principle of electrostatic capacitance, in which aluminum oxide is used to increase the energy storage.
