Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are very commonly used in many consumer appliances, such as computers, digital cameras, and other consumer electronics. They are a very popular choice for use in circuits because of their low cost, and their relative high capacitance values.

860040478014 is a popular model of aluminum electrolytic capacitor. It has a low ESR (equivalent series resistance) and a wide temperature range of -55 to 135°C. This capacitor has a rated capacitance of 470 uF, which makes it ideal for high-frequency switching applications. This capacitor also has good endurance in terms of load life and ripple current.

Application Fields

Aluminum electrolytic capacitors are used in a variety of applications. Most commonly, they are used in filtering and energy storage applications. They are also used for signal coupling, signal smoothing and protection, power supply decoupling, and as timing components.

High-capacity electrolytic capacitors are typically used in power supply filtering. The capacitor helps reduce the ripple in the output of the power supply, resulting in low noise and less distortion in the signal. This type of capacitor is also used in power factor correction and power factor optimization circuits.

Low-capacity electrolytic capacitors are used in a variety of different circuits. They are commonly used as signal coupling capacitors in audio applications, where they act to block direct currents and allow alternating current to pass through. They can also be used as signal filtering capacitors in video applications, where they reduce video noise, improve video signal quality, and help reduce picture artifacts.

Aluminum electrolytic capacitors can also be used as timing components. They can produce a delay when the current is passed through them, so they can be used to create delay lines and time-delayed circuits.

Working Principle

The working principle of an aluminum electrolytic capacitor is fairly simple. It consists of two aluminum foil sheets, which are separated by an electrolytic paper and soaked in an electrolyte. When an electrical current is applied to the capacitor, it causes a chemical reaction at the electrodes, which stores the electrical charge.

The electrolytic paper acts as an insulator, preventing the charges from leaking out of the capacitor. The electrolyte is a mixture of sulfuric acid and other organic compounds, which helps increase the capacitance of the capacitor. This capacitance is measured in Farads (F).

The size of the aluminum electrolytic capacitor is determined by the size of the aluminum foil sheets, the thickness of the electrolytic paper, and the amount of electrolyte that is used. The capacitance of the capacitor is also affected by factors such as surface area, temperature, and frequency of the current.

Aluminum electrolytic capacitors are very reliable and have a long life. The life expectancy of an aluminum electrolytic capacitor can range from a few thousand hours to several years, depending on the type of capacitor and its operating conditions.
