Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are some of the most widely used capacitors on the market today, thanks to their combination of low cost, high-energy storage capability, and relatively long life. The 139R882M020AA2B series is a range of aluminum electrolytic capacitors that feature a solid electrolyte with a dielectric material of a high-quality aluminum oxide. This series is designed for use in a wide variety of commercial and industrial applications such as audio/video equipment, communications and networking equipment, medical device applications, automotive applications, and power supplies.

Construction and Features:

The 139R882M020AA2B series is constructed using a solid electrolyte of cyanoethylated polypropylene film as the dielectric material. This dielectric material features a low losses layer which provides a good insulation resistance and a high dielectric constant. This allows for a much larger capacitance than is generally available from other types of aluminum electrolytic capacitors. The construction of these capacitors also includes a stainless steel braid and a non-inductive coating. This combination helps to reduce the leakage of the lead wires and provide an additional layer of protection.The 139R882M020AA2B series has several performance features that make it ideal for a wide range of applications. The most important of these is the low equivalent series resistance (ESR). This feature allows for the capacitors to efficiently store and release energy over a wide range of temperatures. The capacitors also feature a high ripple current which allows for a high ripple power to be stored and released. Additionally, the capacitors have a high internal capacitance which helps to prevent voltage drop over time.

Applications:

The 139R882M020AA2B series is designed primarily for use in applications involving high-voltage power systems. These capacitors can be used to store and release energy for rectifier, motor and transformer circuits. They are also well suited for use in power supplies and converters, medical equipment, and other high-power applications. The use of these capacitors in power electronics applications can help to improve the performance and efficiency of the system.The 139R882M020AA2B series is also an ideal choice for intermittent discharge and storage systems. These capacitors are capable of storing a large amount of energy and can do so for extended periods of time. They are also capable of storing energy at a rate much higher than other types of capacitors, which makes them ideal for applications where the power is being changed quickly.

Working Principles:

Aluminum electrolytic capacitors work by storing electrical energy and releasing it on demand. In this type of capacitor, two electrodes (an anode and a cathode) are placed in a liquid electrolyte such as an aqueous solution or organic solvent. When a voltage is applied across the electrodes, ions from the electrolyte are attracted to the electrodes and form a dielectric layer. This layer allows for electrical energy to be stored in the form of charge on the anode and cathode. When the capacitor is discharged, the electrical energy stored in the form of charge is released from the capacitor.The 139R882M020AA2B capacitor series is designed to be able to handle high-voltage power systems. This is because of their strong construction and large capacitance. As such, these capacitors are capable of storing more energy for longer period of time. Additionally, the internal capacitance is much higher than other aluminum electrolytic capacitors, giving them the ability to operate over a wide temperature range.

Conclusion:

The 139R882M020AA2B series capacitors are designed specifically for high-voltage power systems and other power electronics applications. The capacitors feature a solid electrolyte of cyanoethlemated film as the dielectric material, which provides excellent insulation and a high dielectric constant. The capacitors also offer a low equivalent series resistance and an internal capacitance higher than other aluminum electrolytic capacitors, allowing them to efficiently store and release energy over a wide range of temperatures. The capacitors are ideal for use in power supplies, medical devices, and other high-power applications.
