Aluminum Electrolytic Capacitors

EEU-EB1E102B Application Field and Working Principle

Aluminum electrolytic capacitors are built from two aluminum foil electrodes with an electrolytic paper separator between them. The electrolyte serves as the working medium which is a liquid, wet or solid. They comprise of a metalized anode aluminum can and a fluid filled double layer formed by an oxide film on its surface and a liquid medium used as an ion conduction. These capacitors are mainly used in ripple suppression, high frequency noise filtering, spike suppression, motor speed adjustment, peak current boosting and other electronic circuits.The EEU-EB1E102B series is a range of polarized aluminum electrolytic capacitors with snap-in terminals, a rated voltage of 1000 Volts DC and a wide capacitance range from 1µF to 470µF. They are mainly used in power supplies, voltage regulators, inverters, motor drives and other general industrial applications. The use of organic polymer electrolytes provides excellent temperature and humidity characteristics, low impedance and extended operational life.The operating principle behind EEU-EB1E102B aluminum electrolytic capacitors is based on the electrolysis of the electrolyte medium and the aluminum oxide layer formed on the anode foil. The oxide layer acts as a dielectric between the two aluminum electrode foils and allows for a high capacitance value. In addition, the electrolyte improves the electrical properties and increases the dielectric strength of the oxide layer.An electrolyte is a liquid or gel that contains free ions which can move about. It is used to conduct electricity across boundaries like an electrical double layer. During the operation of an aluminum electrolytic capacitor, the ions in the electrolyte medium move through the ion transport area between the electrodes and the separator. In this area, a double-layer forms and acts like a capacitor, giving the device its capacitance.The anode foil is insulated by the oxide layer, which prevents current flow between the two electrodes. When a voltage is applied across the aluminum foils, the dielectric strength of the oxide layer breaks down allowing electric energy to be stored in the form of electric flux lines, thus providing the desired capacitance.In order for an aluminum electrolytic capacitor to work reliably, its design should follow certain guidelines. The capacitance and the voltage ratings should always be kept within the permissible values, the device should always be provided with reliable insulation, and the operation temperature should be kept within reasonable limits. Furthermore, all of the components should be of high quality and the connections should be mechanically and electrically reliable.In summary, the EEU-EB1E102B series of aluminum electrolytic capacitors are highly reliable and efficient components used in a variety of applications. They are an excellent choice for all sorts of electronic devices due to their high capacitance and dielectric strength. Furthermore, because of their snap-in terminals and wide range of capacitance values, they can easily replace any capacitors that are no longer available in the market. Lastly, the operation and design of these capacitors should always follow the guidelines mentioned above in order for them to work properly and provide optimum performance.
