Aluminum electrolytic capacitors are widely used in a variety of applications due to their ability to store electrical energy for smaller periods of operation. The ALS81C333QW200 is a type of electrolytic capacitor designed for higher operating temperatures and long life. It is built using an anode aluminum foil substrate which is rolled into a cylindrical shape and is then coated with a dielectric oxide film. The capacitor is then filled with electrolyte and sealed with a plastic/epoxy material.

The ALS81C333QW200 is designed to provide contant and reliable stored energy for a maximum of 20,000 hours. The capacitor is rated to a temperature range of -55°C to +105°C and a voltage rating of 2000Vdc. It is particularly suitable for applications where high temperature and long life are required, such as power supplies, inverters, UPS, and LED lighting systems.

The operating principle of an aluminum electrolytic capacitor is the same as a regular capacitor: An electric field is generated when a voltage is applied across two plates (the dielectric). The field will cause electrons to move from one plate to the other, thus storing energy. The stored energy depends on the size of the plates and the dielectric material between them. In an electrolytic capacitor, the dielectric is provided by a thin oxide film on the anode. This thin oxide film dramatically increases the capacitance of the capacitor compared to other types of capacitors.

The ALS81C333QW200 is an example of a long-life, high temperature aluminum electrolytic capacitor. Its robust construction and excellent performance makes it an ideal choice for a variety of applications where reliability and long life are needed. With its proven reliability, it is sure to be a popular choice for many industrial and consumer applications where long-term reliability is required.
