Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are a type of capacitors that rely on an electrolytic solution for its operation. They are extensively used in multiple applications, especially the PSU6435 application. The PSU6435 is an aluminum electrolytic capacitor that was specifically designed for switch-mode power supplies.An aluminum electrolytic capacitor is composed of two aluminum foil sheets, separated by a porous membrane material. The aluminum foil sheets are coated in an electrolytic solution, which acts as the electrolyte and provides a charge to the capacitor. The mechanism of this capacitor relies upon the formation of a thin insulating oxide layer on the aluminum sheet. This layer allows for a high level of charge storage capacity and it is also responsible for the high voltage rating of these capacitors.The capacitance of an aluminum electrolytic capacitor depends on the length, width, and thickness of the parts that make up the capacitor. The amount of capacitance also depends on the temperature - the temperature influences the size of the oxide layer that forms on the aluminum foil.The PSU6435 application requires ultra-low ESR (equivalent series resistance) and it does this by employing a stack of three aluminum foil layers. These layers are separated from each other by a superior dielectric oxide layer. The triple-stacked layers can significantly reduce the ESR, which improves the switching ability of the power supply. Furthermore, it also provides ultra-low inductance, which is beneficial for improving the efficiency of the power supply.The PSU6435 also utilizes proprietary electrode termination technology that segregates the positive and negative electrode from each other. This also helps to reduce ESR and effectual inductance. Another important property of the PSU6435 is its high ripple current capability. This means that the capacitor can withstand large pulses of current, supporting the requirements of the power supply.In conclusion, the PSU6435 is an aluminum electrolytic capacitor, specifically designed for switch-mode power supplies. It is composed of aluminum foil layers coated in electrolytic solution, with the capacitance depending on the size of the oxide layer formed. The PSU6435 employs a triple-stacked configuration to reduce ESR and inductance, with proprietary electrode termination also helping to reduce these values. Furthermore, the capacitor’s high ripple current capability makes it suitable for switch-mode power supplies.
