Aluminum electrolytic capacitors are one of the most common types of capacitors. They are widely used to store energy in the form of an electric field. The ALS81A202DE200 is a type of aluminum electrolytic capacitor. It is an axial-leaded, non-polarized capacitor with a capacitance of 82μF ±10%.

Aluminum electrolytic capacitors are made from a very thin, porous aluminum oxide dielectric sealed in an aluminum can. The can serves as the positive electrode and the thin aluminum oxide layer serves as the negative electrode. Between the two electrodes is a liquid electrolyte, usually containing organic solvents and ionic salts. When an electric current passes through the circuit, the electrolyte forms a conductive bridge between the two electrodes, allowing electrons to move between them. This creates an electric field, which stores electrical energy in the form of a charge.

The ALS81A202DE200 is well-suited for high-ripple current applications such as audio and power supplies. It is capable of withstanding high voltage, up to 630V DC and 125V AC, and high temperature, up to -40 °C to + 85°C. The capacitance is rated for 85 °C and the dissipation factor (D. F.) is 0.25%. The maximum leakage current is 20μA, and the capacitor is capacitance-stable even with a long operating life. It also has a low ESR, allowing for minimal power loss in operation.

The ALS81A202DE200 is primarily used in switching power supplies and DC-DC converters, as well as in the output stages of linear amplifiers and other audio amplifiers. It is also suitable for energy storage and buffering applications, as well as for filtering and decoupling signals in communication equipment. It may also be used in frequency conversion circuits as an AC capacitor.

To conclude, the ALS81A202DE200 aluminum electrolytic capacitor is a reliable, high-performance capacitor well suited to applications with demanding operational environments. It is capable of withstanding high voltage and temperatures, with a long lifetime despite its small size. Its ability to store large amounts of energy in the form of an electric field makes it an essential component in many types of power, audio, and communication equipment.
