Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors are a type of capacitor that offers a large capacitance in a relatively small volume. They are composed of two aluminum foil plates, separated by separator and impregnated with an electrolyte. Electrolytic capacitors are mainly used in power electronics applications such as high-voltage DC-DC converters, motor drives, current surges in welding, and energy storage.

AFK107M80H32B-F Aluminum Electrolytic Capacitors Application Field and Working Principle

AFK107M80H32B-F Aluminum Electrolytic Capacitors are generally used in audio frequency systems and advanced digital circuits. It is a non-polarized, large capacitance capacitor with a relatively low ESL. The capacitor is a rectangular solid type with thickness and mounting holes. With its superior size, high grade organic solid insulation, and anode or cathode identification, AFK107M80H32B-F is ideal for usage in audio frequency systems, with its high-end capacitance and low parasitics.

The working principle of AFK107M80H32B-F Aluminum Electrolytic Capacitors is based on the Faraday principle, a principle of induction developed by Michael Faraday in 1844. This principle states that when a conductor such as an aluminum plate is exposed to a varying magnetic field, an electromotive force (EMF) will be generated. When an electrolyte is added to the conductor, the EMF acts as an electrical field, impeding the flow of current. This path from the anode to the cathode of the capacitor is broken, which causes a capacitance effect, resulting in the storage of electrical energy.

Most AFK107M80H32B-F Aluminum Electrolytic Capacitors are rated at a maximum operating voltage of 80V, and are suitable for operation in temperature ranges from -15°C to 85°C. The capacitance of each electrolytic capacitor is determined by the active material, the surface area, the thickness of the polarizing film, and the voltage. The life of the capacitor is primarily determined by the impregnation method, the temperature, and the voltage.

Due to their low ESL, long life, and high operating voltages, AFK107M80H32B-F Aluminum Electrolytic Capacitors are perfect for applications in audio frequency systems, power supply circuits, and high-voltage DC-DC converters. Manufacturers of sources such as cars and trucks rely on these capacitors for their accurately rated peak and average currents, low ESR (Equivalent Series Resistance), and low ESR levels at high temperatures.
