Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a polarized device constructed from tantalum foil, an electrolyte material of typically manganese dioxide, and two aluminum foils. The device carries a working voltage of up to several hundred volts, and also carries a capacitance from a few microfarads to tens of farads. It is used in various applications like electric fence systems, automatic voltage regulators, lighting dimmers, switching applications, and many other power system purposes.

865080453013 Application Field and Working Principle

The 865080453013 Aluminum Electrolytic Capacitor is a mid-to-high voltage rated Capacitor widely used in DC switching and power electronic circuit applications. It has a wide range of operating temperatures from -40℃ to +105℃, and also features a very low impedance. This device works by allowing a certain amount of charge to flow between two electrical conductors, thereby storing a certain electric potential energy in the capacitor over time. As electric charge accumulates, the capacitance increases, making the device more suitable for various applications.

Applications

The 865080453013 Aluminum Electrolytic Capacitor is used in a wide variety of applications including pulsed or DC power supplies, DC-to-DC converters, audio applications (dynamic loudspeakers and subwoofers), as well as power amplifiers. It can also be used for many different types of low- and high-voltage applications, such as LCD backlighting, voltage regulation circuits, and even as a replacement for tantalum capacitors due to its extremely low equivalent series resistance (ESR).

Working Principle

The working principle of the 865080453013 Aluminum Electrolytic Capacitor is based on the double-layer electric field or storage effect. This type of capacitor stores electric energy between two confined layers of electrodes – the anode (positive) and the cathode (negative). A layer of electrolyte material exists between the two layers, facilitating the transfer of charge between them, even when the applied voltage exceeds the device’s rated voltage. In addition, this electrolyte material also helps to suppress any leakage current, resulting in an acceptable level of performance in most applications.

Conclusion

The 865080453013 Aluminum Electrolytic Capacitor is a versatile and reliable device suitable for a wide range of applications. With its wide range of operational temperature limits, low ESR, and extremely low leakage current, it is easily one of the most reliable capacitor types available in the market today. Its ability to store electric potential energy for long periods of time makes it ideal for use in DC power supplies, DC-DC converters, voltage regulation circuits, and many other electronic circuit applications.
