UPW2C331MRH

Aluminum electrolytic capacitors are a type of capacitor, with special characteristics enabled by using an electrolyte as one of its two electrodes. These capacitors are specially designed to offer high values of capacitance in small packages. The international development of electrolytic capacitors was mainly driven by the emergence of electrical industrialization during the 19th century.

The UPW2C331MRH is a molded radial leaded aluminum electrolytic capacitor, widely used in pulse and filter circuits. This type of capacitor typically has a solid cylindrical aluminum outer shell that houses an oxide dielectric film, with capacitance determined by the surface area of the combining surfaces. A liquid electrolyte is fixed in the capacitor and acts both as an electrical carrier and a chemical activator to ensure extended and stable life.

The UPW2C331MRH is composed of a cathode, anode, and internal electrolyte. The aluminum cathode foil is the positive terminal of the capacitor, and an oxide film is formed on the surface that works as an insulator and dielectric fluid. The anode is composed of aluminum foil with an electrolyte paste on top, separated by an insulating paper. The super-low ESR of this capacitor allow it to be widely used in an extensive range of electronic applications, particularly in timer circuits, DC/DC, line filters, and power supplies.

The working principle of the UPW2C331MRH is based upon Faraday\'s law of electrochemistry. It states that the amount of charge stored by a capacitor in a closed circuit is directly proportional to the difference in electric potential between its two electrodes. The voltage rating or dielectric strength of the electrolytic capacitor increase as more charge is stored across two terminals, creating a higher electric field.

The UPW2C331MRH capacitor also offers unique characteristics and benefits not available with other capacitors. The high capacitance and low impedance of the capacitor makes it suitable for power supplies and signal conditioning applications. With its low ESR and low temperature coefficient, it can withstand strong transient voltages while providing stable electrical performance. Additionally, it has a long shelf life, in which it can store energy for many years after installation.

The UPW2C331MRH aluminum electrolytic capacitor is an ideal solution for many applications that require high capacitance values in a compact size. Its long life, low ESR, and low temperature coefficient allow it to meet a variety of fast-changing performance requirements. As a reliable capacitor with proven reliability, it has become an essential component in a wide range of electronic applications.
