Aluminum electrolytic capacitors are a type of capacitor typically used in electronic production, such as high-frequency circuits, high-speed circuits, pulse circuits, high-voltage circuits, and high-power circuits. This type of component is widely used in the industry because of its high-capacity density, low equivalent series resistance (ESR) and low cost. An example of aluminum electrolytic capacitors is the EKMT421VSN391MR45S.

The EKMT421VSN391MR45S is a high-capacity aluminum electrolytic capacitor with a maximum operating voltage of 450V and a capacitance of 391µF. It is designed to have a long service life of 10,000 hours at 105°C in a range of temperatures. With its high voltage capability and long service life, the EKMT421VSN391MR45S is suitable for use in a variety of applications, such as filter networks, audio equipment, power supplies, and motor controllers. The capacitor is also capable of producing a low ESR at a nominal frequency of 120kHz and a high ripple current rating of 1150mA.

The working principle of aluminum electrolytic capacitors such as the EKMT421VSN391MR45S is based on the theory of Faraday\'s law of electrolysis. When a voltage is applied to the two terminals of the device, a current flows through the electrolyte, which is a solution of eutectic salts. This current causes the formation of a layer of oxide or hydroxide ions at the cathode surface. This layer of ions is called the electric double layer. The electric double layer acts as an insulating barrier between the two electrodes, allowing the capacitor to store energy, which can be used to reduce the voltage ripple of power supplies, filters signals, and improve signal quality.

The aluminum electrolytic capacitor is composed of several parts, such as an anode foil, an anode lead, a cathode foil, an electrolyte, a central separator or dielectric, a cathode lead, and a sealing housing. The anode of the capacitor is usually made of aluminum foil, while the cathode is typically made of a conductive paper or non-conductive polymer material. The electrolyte is usually a solution of eutectic salts, which serves to provide a connection between the two electrodes and to help in the formation of the electric double layer. The separator or dielectric is a layer of insulation between the two electrodes that provides a barrier to prevent the electric current from passing from one electrode to the other.

The EKMT421VSN391MR45S aluminum electrolytic capacitor offers high performance and reliability for a variety of different applications. It has a high capacity, a low series resistance, and a long service life.
