Aluminum electrolytic capacitors are electronic components that stores electric energy with its metal oxide film electrodes and aluminum foil as the electrodes of the electrolytic capacitor. They are widely used in many industries, such as aerospace, automotive, communications, medical, office equipment and industrial controls. The UVR1A331MEA is an aluminum electrolytic capacitor developed by Nippon Chemi-Con authorized for use in those industry fields. It is axially leaded type and contained in a cylindrical case. UVR1A331MEA of Nippon Chemi-con\'s aluminum electrolytic capacitors is a very useful product, designed for the specific purpose of protecting equipment from electrical noise and interference. Its principal application lies in the protection of semiconductors and other components from transient voltage peak voltages due to lightning, electric power supply, switching operations, and sudden voltage drops.This aluminum electrolytic capacitor is characterized by its high voltage and current withstanding ability, non inductive design, long service life, and low leakage current. It’s operating temperature range is -40°C to +85°C. The capacitance of UVR1A331MEA is 330μF and its working voltage is 350V. The lead pitch is 10mm and the total case or body diameter is 18.3mm. The principle of an aluminum electrolytic capacitor is simple. It has a dielectric film composed of aluminum oxide on the surface of aluminum which has a capacity of about 5000V/μm. The inner part is a solution of electrolyte in which an anode of aluminum oxide is submerged. When voltage is applied, the positive ions in the electrolyte are attracted to the anode and a thin layer of aluminium oxide forms on the anode. This layer forms the dielectric layer of the capacitor.The UVR1A331MEA has a long life due to the use of low Evaporation Solvent Aluminum Electrolyte static electricity leakage, increased temperature resistance and improved impedance. It is graded according to two factors: contamination resistance and voltage characteristics reliability. Specifically, it features a high ripple current capacity and small size, long life span, low impedance, low temperature coefficient and high reliability. In addition, this aluminum electrolytic capacitor also features good thermal stability and steady performance in various conditions. In conclusion, UVR1A331MEA aluminum electrolytic capacitor is an excellent choice for applications requiring high voltage and current withstanding ability, like in aerospace and automotive equipment protection against transient voltage peak voltages due to lightning, electric power supply, switching operations, and sudden voltage drops. It is able to provide maximum efficiency and consistently reliable performance over a long service life.
