Aluminium electrolytic capacitors, or simply aluminum capacitors, are capacitors that exploit the ribbed aluminum anode design employed by electrochemists. Aluminum capacitors are typically end-of-life electrolytic capacitors. Many are polarized and characterized by their broad temperature range, low equivalent series resistance (ESR) and long service life.

B43821F1686M000 is a type of aluminum electrolytic capacitor that has a wide range of applications in many electronic devices like digital music players, lighting and electrical toys, computers, as well as instrument, communication, and industrial control equipments. It has a capacitance range from 4.7uF to 200uF, and operates within a temperature range of -40~105°C.

The working principle of aluminum electrolytic capacitor is based on the process of charging and discharging of electrolytes. An aluminum-oxide film is produced on the surface of an aluminum anode by anodization process, forming a dielectric for capacitive behavior. The electrolytic material of the capacitor allows an anION to pass through it which then combines with the anode to form an electric double layer. Then, an elctronic charge would be stored by the anode or cathode. The amount of charge stored in the capacitor is proportional to the ratio of capacitive (polarized) material available to it, as well as the voltage applied to it. When the applied voltage is reduced below a certain point, the charge stored within the capacitor is gradually leaked of, as the charge is affected by the electrolyte\'s AC impedance.

B43821F1686M000 aluminum electrolytic capacitors have low electrical losses, and high ripple current handling and energy storage capabilities. Furthermore, they exhibit superior voltage proof characteristics, allowing them to handle large voltage swings with very low leakage current. These capacitors are especially suitable for energy storage and filtering, making them ideal for applications in power electronic systems that require large energy capacity.

In addition to their electrical advantages, aluminum electrolytic capacitors are extremely reliable and offer long service life over a wide temperature range. Furthermore, they have very low cost when compared to other types of capacitors, and are highly versatile, being available in a range of capacitance, voltage ratings, and physical dimensions.

B43821F1686M000 aluminum electrolytic capacitors are widely used in many different areas, including power supplies, audio amplifiers, and digital switching regulators. In addition, they are also used in car audio amplifiers and in electric motors, and are also commonly used in many other applications such as TV receivers, CCTV systems, and other consumer electronics.
