Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors (AECs) are commonly used in many electronic design and industrial process applications. They are constructed of a rolled strip of aluminum or tin-plated aluminum foil that is etched with an oxide layer to act as a dielectric. The capacitor has two electrodes, one positive (anode) and one negative (cathode), and is filled with a liquid electrolyte that conducts electricity.

The capacitor\'s electrical properties are determined by its dielectric strength, capacitance, temperature coefficient, voltage rating and rated frequency. It also has a high self-inductance, low dielectric absorption and low voltage coefficient, and is capable of handling high voltage and frequency. These characteristics make them ideal for use in a wide range of applications, including power supplies, filters, amplifiers and electronic circuits.

The ALS81H361DA450 is one of the most commonly used iron core aluminum electrolytic capacitors. It has a temperature range of -40 to +105°C, a voltage rating of 450 volts, and a rated current of 310A. It is designed to have a high dielectric strength of 1,200 volts, a high capacitance of 9.6mF, and a low voltage coefficient of 0.0018.

As the name suggests, the capacitor is made up of an Al-L-S (Aluminum-L-S) core, which consists of a ferrite material surrounded by two layers of aluminum foil. The ferrite core serves as the anode and provides the material for the electrolyte. The two layers of aluminum foil serve as the cathode and provide the necessary mechanical stiffness that is required for the capacitor to work. Due to its high dielectric strength, it is suitable for high voltage, high frequency, and high current applications.

In terms of working principle, the capacitor acts like a battery in reverse. When a voltage is applied across the capacitor, an electric current flows through the electrolyte. This electric current acts on the electrode in such a way that it releases electrons into the electrolyte, which then release energy and capacitively store energy. This energy is then released when the capacitor is discharged, producing the desired electrical effect.

Because of the high dielectric strength and relatively low rates of power loss, the ALS81H361DA450 is an ideal choice for a variety of applications, including UPS systems, motors, printers, TVs, audio amplifiers, and even medical and military equipment. It is also popular for use in energy storage systems due to its high self-inductance and low voltage coefficient. As such, it is an invaluable component for applications that require high levels of reliability and performance.
