Aluminum electrolytic capacitors are energy storage devices that are widely used in various fields of electronic industry. They have a good energy storage performance and a number of characteristics such as large capacitance, high voltage performance, low equivalent series resistance (ESR), and low temperature coefficient of capacitance (TC). The LGU2D681MELC aluminum electrolytic capacitor is an extended temperature version of the conventional aluminum electrolytic capacitor. It provides excellent high temperature reliability and long life characteristics while achieving a much lower ESR even in large capacitance values. The device comes with a non-polarized design, making it suitable for use in both polarized and non-polarized circuits.The LGU2D681MELC aluminum electrolytic capacitor can be used in a wide range of applications. It has been proven to be effective in commercial and industrial power supplies, voltage regulators, switching power supplies and resonant converters, as well as a wide range of consumer applications such as audio equipment and home appliances. The device is also ideal for motor drives and advanced motor control systems, allowing for a larger energy storage capacity.The working principle of the LGU2D681MELC aluminum electrolytic capacitor is based on the electrochemical nature of the aluminum oxide film on its anode. The thin oxide film consists of an anodically polarized electrolyte, and allows for current to flow between the anode and the cathode when a voltage is applied across the terminals. This electrical current is stored in the electrolyte, forming an electric double-layer capacitor, or EDLC.When the voltage is applied, a reverse current is generated through the oxide film and the electrolyte, resulting in the formation of an electric double-layer between the anode and the electrolyte. This electric double-layer serves as the battery that stores the energy, and the capacitance depends on the surface area of the electrodes and the thickness of the oxide film.The LGU2D681MELC aluminum electrolytic capacitor is also designed to provide a low ESR, even at a high operating temperature. This is achieved through its unique design, which utilizes a large surface area with a very thin oxide film, resulting in a large capacitance. Additionally, its capacitance values remain fairly constant for a wide range of temperatures, allowing for a good energy storage capability.The LGU2D681MELC aluminum electrolytic capacitor is an ideal device for many applications, allowing for higher power density and longer life under extreme high temperature conditions. Its excellent energy storage characteristics make it especially suitable for consumer applications, as well as various other power management applications.
