Aluminum electrolytic capacitors are electrochemical components of electrical equipment composed of aluminum foil, electrolyte, separator and other materials. The use of aluminum foil in the production of electronic components allows for a higher capacitance-to-size ratio, making it ideal for applications where larger capacitors would be prohibitive.The LGU2E821MELC series of aluminum electrolytic capacitors is manufactured by Nichicon Corporation in Japan. This model fits the 200V to 450V voltage range and offers current ratings of 85-180µF. It is a non-pole radial type, featuring an insulated case with larger volume than the conventional models, allowing extra freedom in designing circuit.The model LGU2E821MELC aluminum electrolytic capacitor offers excellent performance at a competitive price. It has a low equivalent series resistance (ESR), providing low heat generation and excellent temperature characteristics for stable operation. The operating temperature range is -40 to +105°C, which is suitable for most system requirements. At the same time, it features improved load life characteristics which is more than double the expected life of comparable products. The low ESR and high rated current capability of this series aluminum electrolytic capacitor make it ideal for applications where switching power supplies are needed.The process by which aluminum electrolytic capacitors work is based on the principle of Faraday’s law. When a current is applied across an electrolyte, aluminum ions deposit on one side of the anode and oxygen ions on the other side, forming a porous anode layer. When this layer thickens, a barrier is created that impedes the flow of current. This build up of negative charge increases the capacitance of the device.The LGU2E821MELC series aluminum electrolytic capacitor is designed with a variety of applications in mind. It is suited for decoupling, filtering and storage of electrical energy, commonly found in digital and analogue circuits. It is also suitable for coupling, noise suppression, and uninterruptable power supply systems. The capacitance and voltage range make it suitable for use in both electronic and high-voltage power systems.The aluminum electrolytic capacitor series offered by Nichicon has been developed to provide a high level of reliability and consistency over a wide range of temperatures. The self-healing nature of these capacitors allows them to tolerate application conditions without suffering failure due to electrical breakdown. Compared to other types of capacitors, aluminum electrolytic capacitors can withstand more shock and vibration, which makes them suitable for applications in harsh environmental conditions.In conclusion, the LGU2E821MELC aluminum electrolytic capacitor series provides excellent performance with a number of application possibilities. It has a high capacitance to size ratio and comes with a wide range of voltage and current ratings, making it ideal for a diverse range of applications. The low ESR and high rated current capability of this series aluminum electrolytic capacitors make them especially suitable for use in switching power supplies. Furthermore, they are designed to provide a high level of reliability and consistent performance over a wide range of temperatures, and reliable operation in high shock and vibration environments.
