Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used and one of the most popular types of capacitors available on the market. They are polarized, meaning they have a positive and negative terminal. This type of capacitor has an electrolyte sandwiched between two aluminum foils with a paper separator. Its structure gives it an excellent voltage rating and high capacitance values in very small volumes compared to other types of capacitors.

UPW2E2R2MPD Application Field

The UPW2E2R2MPD is a surface mount aluminum electrolytic capacitor. This capacitor is a polarized radial lead component that is commonly used in consumer, industrial and military applications. This type of capacitor has a wide range of application fields. Some of the applications it is used in includes electronic circuits, audio and video equipment, computers, instrumentation, communications equipment, broadcasting equipment, radio equipment, etc.

Working Principle of UPW2E2R2MPD

The working principle of an aluminum electrolytic capacitor is relatively simple. It consists of two aluminum foil electrodes that are insulated from each other with an oxide layer. An electrolyte, usually an aqueous solution, acts as the dielectric. An electric field is established within the dielectric when a voltage is applied on the two aluminum foil electrodes. In addition, the capacitor acts as an energy storage device, storing electrical energy in the form of electrical potential energy. When the voltage is removed, the capacitor discharges, releasing the electrical energy.
