UPW0J270MDD

Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, often referred to as simply an electrolytic capacitor, is a type of capacitor which relies on an electrolyte as its dielectric. They offer relatively high capacitance values and are readily available in a range of shapes, sizes and capacitance values. UPW0J270MDD is one of the most common types of aluminum electrolytic capacitors in use today.

Application Field

UPW0J270MDD capacitor is used in a variety of electronic circuits, such as in radio transmitters, audio and video equipment, control systems, diagnostic systems, computers, and power supplies. They can also be found in electric motors, LED lighting, UPS systems, and even solar power systems.

Working Principle

Aluminum electrolytic capacitors rely on an electrolyte having ions, that is, an ionic conductor, as the dielectric material. When a voltage is applied across the two leads, the electrolyte conducts the current between them. This current causes a thin oxide layer to form on both leads and acts as a dielectric between them, blocking the flow of current. The oxide layer is the main source of dielectric, and it determines the capacitance of the capacitor.

As the capacitance increases, the direction of the current is reversed and the oxide layer is gradually reduced, resulting in a thinner dielectric. This process continues until the oxide layer is completely gone and the current is interrupted. This is why aluminum electrolytic capacitors usually start with a high capacitance value and then steadily decrease over time.

Aluminum electrolytic capacitors are also known for their high voltage tolerance, as compared to other types of capacitors. This allows them to be used in applications where high voltages are present, or when high frequencies are needed. Additionally, they are very resistant to temperature and can be used in applications that require high temperatures.

UPW0J270MDD aluminum electrolytic capacitors are quite popular in the electronics industry due to their combination of reliable performance, robust construction and a wide range of sizes and capacitance values. They are used to provide power to circuits, boost signal and reduce noise, and store power for later use.

Overall, aluminum electrolytic capacitors are a reliable and cost-effective choice for many electronic applications. They offer superior performance, superior reliability, and superior features and are a great choice for anyone looking for a reliable and cost-effective capacitor solution.
