Aluminum Electrolytic CapacitorsAn aluminum electrolytic capacitor is a polarized capacitor whose anode electrode is made of a pure aluminum foil with an etched surface and is covered with an insulating oxide layer. The electrolyte, which is usually an aqueous solution of ammonium borate or similar electrolytes, acts as the cathode.Aluminum electrolytic capacitors (aluminum caps) have an exceptionally high volumetric efficiency and cost effective materials and manufacturing processes which make them the preferred choice for large capacitance and high voltage applications. Moreover, in comparison with other metals such as tantalum, they have an extremely low equivalent series resistance and equivalent series inductance, making them highly suitable for applications that require high frequency and transient performance.Due to their high current handling capability, aluminum electrolytic capacitors are used in a variety of applications ranging from low voltage power supplies, switching power supplies, voltage regulators, and oscillators to radio-frequency amplifiers, x-ray tubes and radar systems.The 380LQ182M180K042 is a type of aluminum electrolytic capacitor and its application field as well as working principle can be summarized as follows:Application FieldThe 380LQ182M180K042 is a high voltage aluminum electrolytic capacitor capable of operating at a voltage up to 900V. It is especially suitable for applications where high voltage isolation is needed, such as automotive, telecommunications and industry. It is also widely used in motor drives, high-end audio and power supplies.Working PrincipleAluminum electrolytic capacitors are polarized capacitors that use an electrolyte solution to store electrical energy between two electrodes: a pure aluminum foil and an electrolyte solution. The aluminum foil acts as the anode and the electrolyte solution acts as the cathode.The 380LQ182M180K042 consists of an aluminum anode foil, insulation paper, an electrolytic solution, cathode lead wires and an aluminum case. When the capacitor is energized, an electric field is created in the electrolyte between the positive aluminum anode and the negatively-charged electrolyte. This field creates a double-layer of electric charges that store electrostatic energy.The capacitance of the 380LQ182M180K042 is related to the area of the aluminum anode, the surface area of the insulation paper, the dielectric constant of the electrolyte, and the distance between the two electrodes. When the distance between the two electrodes is reduced through the application of a voltage, the capacitance increases.In addition, the 380LQ182M180K042 is also able to withstand high voltages. This is due to the high dielectric strength of the electrolyte, which prevents arcing and corona discharge between the two electrodes.Due to these characteristics, the 380LQ182M180K042 is an ideal capacitor for applications requiring a high voltage and a high capacitance. It is also highly reliable, as it has a low equivalent series resistance (ESR) and excellent leakage characteristics.
