Aluminum Electrolytic Capacitors: LNU2W682MSEJ Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in electronics and electrical engineering. In the field of aluminum electrolytic capacitor, they are used as the main capacitors in power supplies, noise suppression in automobiles, and commercial electrical equipment. LNU2W682MSEJ series aluminum electrolytic capacitors are specially designed for industrial applications, providing improved dielectric performance in challenging working temperature environments.Aluminum electrolytic capacitors are polarized capacitors composed of an anode and a cathode, usually with one end of the anode marked. The construction of an aluminum electrolytic capacitor is more complicated than that of other types of capacitors. The structure of aluminum electrolytic capacitors consists of an aluminum foil in the form of an electrolyte, which is an anode foil, an electrolytic paper impregnated with a liquid electrolyte, an aluminum oxide film which is formed on the surface of the anode film and acts as an insulating dielectric layer, and a manganese dioxide cathode layer formed on the opposite side of the anode foil.The LNU2W682MSEJ capacitor is a surface-mounted capacitor of the 85 degree series, it works on the principle that the oxide layer of the anode foil is the dielectric. When a DC voltage is applied to the anode foil and the electrolyte, electrolysis occurs, resulting in the formation of the oxide layer on the anode foil. This layer of oxide works as the dielectric between the anode and the cathode. The thickness of this oxide layer affects the capacitor\'s ability to store electrical energy.The LNU2W682MSEJ capacitor can withstand continuous operating temperatures of -40°C to 85°C. Its long-term reliability is due in part to its improved dielectric performance and long-term stability. It also has an increase in reliability under high temperature and voltage conditions due to its improved current handling capability. Its high temperature through-hole design also allows for stabilizing lead wires in high temperature environments.The LNU2W682MSEJ series aluminum electrolytic capacitor is especially well-suited for a variety of industrial applications such as motor drives, solar and uninterruptible power supplies, and so on. Its high temperature and voltage capabilities make it an ideal choice for harsh environment applications. Its capacitance range of 100 μF to 10,000 μF and rated voltage of 6.3 mm to 25V can cover most of the standard needs. The capacitor also comes with a 10 Ω series resistance for better anti-overload protection. Finally, lead-free terminations provide additional reliability and satisfy Lead-Free/RoHS compliant requirements.In conclusion, the LNU2W682MSEJ series aluminum electrolytic capacitor is a high quality capacitor that is suitable for a wide range of industrial and automotive applications. With its robust design, improved dielectric performance, high temperature and voltage capabilities, and 10 Ω series resistance, the capacitor is perfect for harsh environments with demanding requirements.
