Aluminum electrolytic capacitors are widely used in various electronic applications due to their robust construction, low cost and large range of available capacitance values. The EKMM401VNN471MR50S is a surface-mounted aluminum electrolytic capacitor manufactured by KEMET and is designed for use in high-voltage power supply applications. This aluminum electrolytic capacitor is rated for an operating voltage of 450V, and a capacitance of 47uF.The working principle of an aluminum electrolytic capacitor is based on using an electrolyte solution to provide the oxide layer on the anode as a dielectric material. An electrolytic capacitor consists of two aluminum plates, one of which acts as the anode and is coated with an oxide layer, and the other acts as the cathode and is covered with an electrolyte solution. The dielectric layer prevents current flow between the two plates of the capacitor and is known as the “Faraday shield”. The capacitor can then be charged or discharged by applying a voltage to the anode and cathode. The Faraday shield varies in thickness depending on the voltage applied, and thus changes the capacitance of the device.The EKMM401VNN471MR50S is a surface-mounted aluminum electrolytic capacitor that is specifically designed for use in high-voltage power supplies. It has an operating voltage of 450V AC, and a capacitance of 47µF. The device has a rated ripple current of 7.2A, which is the maximum amount of ripple current a capacitor can continuously handle without sustaining any damage. The device also has a voltage derating of 17% to account for voltage drop, as well as a high temperature rating of 105°C.The EKMM401VNN471MR50S is the perfect choice for many high-voltage power supply applications such as boost and flyback converters, DC/DC converters, motor controllers, inverters, rectifiers and other power management applications.
