Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (AECs) utilize an anode of aluminum foil kept under high pressure with an electrolyte of liquid or solid material applied by an organic material separator to form a rugged double layer capacitor (DLC). The electrolyte, acting as a conductive medium, allows a current to flow between the anode and cathode of the capacitor. AECs come in cylindrical cans, disk, and chip packages and their sizes vary from 0.5mm x 0.5mm to 25mm X 40mm.

B43510A9687M007 Application Field and Working Principle

B43510A9687M007 is a type of aluminum electrolytic capacitor which is a can-type capacitors with a maximum working voltage of 450 Volts. The material electrolyte is solid and the capacitor is applied for high frequency applications in everyday life, such as power filtering and energy storage. The working principle of this type aluminum electrolytic capacitors is based on the ability of a solid dielectric (aluminum oxide) to store electrostatic energy when a voltage is applied between a pair of metal plates.

The solid dielectric acts as a barrier layer between two pieces of metal which are the anode and the cathode of the capacitor. When a voltage is applied between the metal plates, a current flows and charges up the anode. As the current flows, the solid electrolyte helps to accumulate the current, creating an electrical field. This electrical field is called the capacitance of the capacitor.

The capacitance of the capacitor is determined by the surface area of the anode and cathode, the thickness of the dielectric, and the distance between the two metal plates. As the distance between the plates increases, the capacitance decreases. The capacitor will remain charged until the voltage is removed. It is important to note that the anode and cathode must remain connected in order for the capacitor to retain its charge.

B43510A9687M007 is mainly used in DC/DC converter circuits where it filters high frequency noise, EMC interference and over voltage transients. It is also applied in motor drive applications including switching power supplies, UPS, DC motor drives, motor drives and other high speed circuits. Its long life also makes it suitable for use in long-term, high-performing, and reliable circuits.

B43510A9687M007 aluminum electrolytic capacitors can handle both high current and mild voltage, and are designed to provide quick response and extensive capacitance per unit volume. Furthermore, they are equipped with surge voltage protection and a long-life capacitor design. As their surge voltage protection exceeds the standard voltage level, it is able to protect the installation from overvoltage and extended voltage range performance.
