Aluminum - Polymer CapacitorsAluminum-polymer capacitors are widely used in various electronic circuits due to their small size, low cost and wide dynamic range. They are also ideal for high voltage applications where a capacitor with high capacitance and low Equivalent Series Resistance (ESR) is needed. The EEF-UE0G271R is a high voltage aluminum-polymer capacitor specifically designed for these applications.ApplicationsThe EEF-UE0G271R is an aluminum-polymer capacitor with a working voltage of 350V, a capacitance of 2200uF, and a maximum rated ESR of 2.0mΩ. It is designed to be used in high voltage power circuit applications requiring capacitors with high capacitance and low ESR values. Additionally, it can also be used in switching power supplies, high voltage drivers, voltage converters and actuator systems.Working PrincipleAt its core, the EEF-UE0G271R is an aluminum-polymer capacitor that utilizes the electrochemical reaction between two electrode materials to form charge. Its construction consists of several layers of aluminum foil, porous substrates that form the separators, and polymer capacitors that fill the space between the electrodes and separators. This assembly is then capped with aluminum foils.When voltage is applied across the capacitor, electrons move from the positive electrode to the negative electrode, resulting in a current which then creates a charge on both electrodes. This charge is stored in the form of an electric field between the electrodes and the polymer dielectric material within the capacitor. The amount of charge stored depends upon the capacitance of the device and the applied voltage.Conclusion The EEF-UE0G271R aluminum-polymer capacitor is specifically designed for high voltage applications that require high capacitance and low Equivalent Series Resistance (ESR). It is largely used in various electronic circuits due to its small size, low cost and wide dynamic range. Additionally, it is ideal for use in power circuits such as switching power supplies, high voltage drivers, voltage converters and actuator systems.
