Aluminum electrolytic capacitors are widely used and most common capacitors in electronic circuits. They use electrolytes as an insulating material between plates which are mounted on a substrate and a dielectric layer of oxide as a charging surface. The two plates are usually made of aluminum, but can also be made of other materials such as copper, titanium, or carbon. They are also known as “electrolytic capacitors,” “electrolitic capacitors,” and “aluminum electrolyte capacitors.”

The 860020272002 aluminum electrolytic capacitor application field involves pulse load circuits, single phase motor drives, electric welding machinery, household appliances, medical and healthcare devices, alternating current meters and other types of electric machinery and power supplies. These components have high reliability, being able to operate in a wide temperature range and in a wide voltage range. They also have high power dissipation, low impedance, and are highly corrosion resistant.

The working principle of aluminum electrolytic capacitors is based on the formation of a thin dielectric layer of aluminum oxide on its surface through the use of an electrolyte solution. The electrolyte solution is composed of a suspension of electrons, ions, and other elements that react with the capacitor terminals to form a thin layer on the surface of the capacitor. The voltage applied to the capacitor is stored on the dielectric layer, allowing for the flow of high currents through the capacitor. This stored energy is released when the capacitor is discharged and the current flow is reduced. The electrolyte also acts as a double insulation between the terminals, preventing short circuits and preventing the capacitor from becoming charged and discharging. Thus, the design of the capacitor must ensure adequate protection of the dielectric layer.

The capacitance of aluminum electrolytic capacitors is determined by calculating the ratio of the surface area of the oxide film to the thickness of the oxide layer. The capacitance and voltage rating of the aluminum electrolytic capacitor are directly proportional to the thickness of the oxide film, making them very suitable for high frequency applications. Other performance parameters such as leakage current and dissipation factor should also be considered when selecting aluminum electrolytic capacitors for a particular application.

Aluminum electrolytic capacitors are manufactured in both surface mount and through-hole configurations and come in a variety of shapes and sizes. Additionally, these components are extremely stable over temperature and humidity, making them especially suitable for use in automotive and other transportation applications. They are also used in many industrial and consumer electronics applications, such as audio amplifiers, television sets, and computer power supplies.

Aluminum Electrolytic Capacitors provide high capacitance, high voltage ratings, and low leakage current and dissipation factor, making them ideal for use in a variety of applications. Through the utilization of electrolyte and the deposition of a thin layer of aluminum oxide on their surface, these components provide excellent performance characteristics and have excellent reliability. Additionally, they are highly resistant to corrosion and can be used in a wide temperature range, making them suitable for many different applications.
