Aluminum - Polymer Capacitors are a type of electrolytic capacitor that uses a polymer as the electrolyte to separate metal surfaces. They are popular for their high energy density, low equivalent series resistance (ESR) and low self-discharge. The individual types of aluminum - polymer capacitors have different characteristics and applications, particularly the AXPC100ARA820MF60G.

Application Field

The AXPC100ARA820MF60G is primarily used in low-voltage and medium-voltage applications, such as motor controllers, inverters, switching power supplies, solar converters and mobile phone boards. It is also suitable for high-frequency circuits due to its low ESR and fast charging/discharging characteristics. The maximum ripple current rating of the AXPC100ARA820MF60G is 8 A at 105°C, making it suitable for high-current, high-frequency circuits. Additionally, it has a wide capacitance range of between 22 uF to 1060 uF, making it suitable for different sized applications.

Working Principle

The working principle of an aluminum - polymer capacitor is based on the electrolyte principle of electrolytic capacitors. Two metal electrodes, one positive (anode) and one negative (cathode), are immersed in an electrolyte. The electrolyte is made up of a solid polymer. When a voltage is applied, an electric field is created between the two electrodes. This electric field causes ions to move from anode to the cathode, forming a semiconductor region and allowing positive and negative charges to move freely through the electrolyte. This results in a capacitance that can store energy and release it when the voltage is removed.

The aluminum - polymer capacitor also has high capacitance per unit volume compared to other types of capacitors, and they are also mechanically robust, with a long lifespan and small equivalent series resistance (ESR). The AXPC100ARA820MF60G also has a large temperature range of -55°C to +125°C, which makes it suitable for use in various applications.

The AXPC100ARA820MF60G is an ideal capacitor for high energy applications as it combines both high capacitance and low ESR with good reliability and a long lifespan. It has a wide range of applications, from motor controllers and inverters, to solar converters and mobile phone boards. Despite its relatively large size, it is still suitable for many high-frequency circuits, due to its low ESR and fast charging/discharging characteristics.
