Aluminum electrolytic capacitors are among the most widely used capacitors in the world. They are used in a variety of applications and are an important component part of many electronic systems. They are used for storing energy, providing smoothing and filtering, and for coupling and decoupling AC signals. The PSU18965B is an aluminum electrolytic capacitor which is developed and manufactured by Philips Semiconductors. It is designed for use in voltage regulation applications that require high capacitance values.

The PSU18965B consists of two solderableelectrodes, an anode and a cathode, separated by a thin dielectricfilm. The anode is composed of aluminum foil on which a coating ofactivate oxide has been formed. The oxide forms a thin, electricallyinsulative barrier between the anode and the electrolyte, and the anodefoil has a high surface area-to-volume ratio. The cathode electrodeis composed of an anode foil and activated carbon particles heldtogether by a binder material. The cathode and anode electrodes areoriented to form two parallel plates and the electrolyte ispumped between them to ensure good contact and electricalcommunication.

The working principle of the PSU18965Bcapacitor is based on Faraday’s law of electrolysis. Faraday’s lawstates that when an electrical field is applied across two solids inelectrolyte, an electrical current will flow. In other words, the application of a voltage across the capacitor will cause a current toflow between the anode and the cathode as ions in the electrolytetravel towards the electrode with the lower potential.

The PSU18965B is designed for voltage regulation applications and can be used in power supplies, UPS systems, inverters, IC regulators, motor drives, and other applications where high capacitance is required. It provides up to 100mF of capacitance with a nominal voltage of 25V and a temperature rating of up to 105°C. It has a low ESR rating, excellent ripple current ratings, and excellent self-healing capability.

The PSU18965B is a reliable and robust capacitor that is designed for high voltage regulation applications. Its high capacitance values make it well suited for power supplies, UPS systems, inverters, and other applications where reliable high capacitance performance is required. Its low ESR rating and excellent ripple current ratings make it an ideal solution for applications that require high voltage regulation capabilities.
