Aluminum electrolytic capacitors are a class of capacitors that use an electrolyte composed of an acid saline solution on aluminum. They store electrical energy and are widely used in electronic circuits because of their ability to store high amounts of charge. The LGU2G391MELB is a special type of aluminum electrolytic capacitor that is highly reliable and has an operating temperature range from -55°C to +105°C. It is widely used in applications such as aerospace, military, industrial and medical.The LGU2G391MELB is composed of a self-healing anode foil with a solvent-resistant coating which provides excellent heat transfer and protection from corrosion. It is also equipped with an internal pressure relief valve that provides protection against overpressure.The primary application field of the LGU2G391MELB is in high-voltage and high-temperature applications. This includes power supplies, switching power supply, industrial motor drives and energy conversion applications such as solar cell arrays, fuel cells and other renewable energy applications.The working principle of the LGU2G391MELB is based on corrosive oxidation of anode material, which creates an electric charge. This charge is sustained on the electrolytic medium which separates the anode and cathode. The capacitance of the LGU2G391MELB is determined by the thickness of the dielectric layer.The capacitance of the LGU2G391MELB is enhanced by the presence of the negative surface charge created by the anode. This surface charge is used to create a barrier between the metal layer and the electrolyte. This prevents the electrolyte from being shorted when a voltage is applied across the LGU2G391MELB.The LGU2G391MELB has a high ripple current rating and a long service life due to its high capacitance and high temperature capabilities. It also has a low ESR (Equivalent Series Resistance) which makes it ideal for applications that require good energy storage.In summary, the LGU2G391MELB is a specialized aluminum electrolytic capacitor that is highly reliable, has a wide operating temperature range, is suitable for high-voltage and high-temperature applications, and has a long service life. It is ideal for use in power supplies, switching power supply, industrial motor drives and energy conversion applications.
