Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors (or AL-CAPS) are a type of electrical capacitors that are characterized by their high electrical leakage and electrical capacitance values. The design of these capacitors relies on thin aluminum oxide dielectric layers with a certain thickness that determine the capacitance value. This makes AL-CAPS very easy to manufacture and their wide variety of available capacitance and voltage values makes them an increasingly popular choice for many types of applications.

UMF0J220MDD1TE Application Field and Working Principle

The UMF0J220MDD1TE aluminum electrolytic capacitor is a polarized, fast-acting capacitor which features a rectangular profile and snap-in terminals for quick and easy mounting. This unit of snap-in aluminum electrolytic capacitors offers excellent impulse characteristics and is specifically designed for the cooling systems of audio equipment. With a rated voltage of 350V, an operational temperature range between -40°C and +85°C and a capacitance of 0.22uF, it is ideal for general purpose circuits.

The UMF0J220MDD1TE aluminum electrolytic capacitor works by storing energy in the form of an electrostatic field between two conductive metal plates. These plates are separated by dielectric layers of oxide deposited on the aluminum, creating a space between the plates in which a charge can accumulate and store energy. The capacitance of this capacitor is determined by the thickness of the oxide layers, while its working voltage value is determined by the amount of current is used to charge its terminals.

The UMF0J220MDD1TE aluminum electrolytic capacitor is mainly used in high-frequency, high-stability circuits or in circuits with frequent interruptions, such as many audio equipment cooling applications. For these circuits, the capacitors are used to filter current, ensuring that it is not affected by abrupt changes in the load or by large transients that could damage the equipment. Due to its exceptional capacitance, voltage, and temperature ranges, it is also a popular choice for simple and complex power supply applications.

In summary, the UMF0J220MDD1TE aluminum electrolytic capacitor is a great choice for audio equipment cooling systems as well as power supply circuits requiring high levels of stability and capacitance over a wide temperature range.
