Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in many electronic device applications. They are known for their high capacitance and long life. The EEV-TG1E221P is a radial-lead aluminum electrolytic capacitor that is designed for use in consumer electronics, medical devices, and industrial control systems.Aluminum electrolytic capacitors are constructed of an anode of an aluminum foil that has been etched into a number of plate-like structures and a cathode of highly porous sintered oxide with perforations. The anode and cathode are separated by a thin layer of oxide, referred to as the dielectric. The dielectric defines the voltage-susceptibility of the capacitor, allowing it to have a substantially higher voltage rating than non-electrolytic capacitors.The EEV-TG1E221P, in particular, is rated for operating temperatures up to +105°C and an attractive voltage rating of 77 volts. It is also designed to withstand a range of temperatures from -55 to +105°C without any permanent deterioration of its performance. This makes the EEV-TG1E221P ideal for controlling high voltage, high frequency AC and DC signals.The EEV-TG1E221P also offers high capacitance and volumetric efficiency. With a capacitance range of 220mF, the EEV-TG1E221P provides a superior capacitance value in a smaller format. This makes the EEV-TG1E221P an ideal choice for applications requiring high capacitance values in a compact package.The EEV-TG1E221P typically finds its application in AC/DC converter applications, or to filters for controlling and suppressing interference in high frequency signals. The EEV-TG1E221P is also suited for applications that require high frequency stability, such as SMPS power supplies, DC/DC converters, and inverters.In more detail, the capacitor is made to operate by passivating the oxide layer on the anode, which forms a dielectric layer. Electrical energy is stored in this dielectric at the interface between the aluminum plate and the electrolyte polymer. When power is applied to the capacitor, ionic current flows in the electrolyte and electrons flow on the plates creating an electrical field. This field produces vibration on the plates, which generates energy stored in the dielectric. This energy is then released by the capacitor back into the circuit when the electrical current is removed.The construction and operating principles of the EEV-TG1E221P make it a reliable and efficient component that can support a wide range of applications in a wide range of operating conditions. Its high voltage capabilities, volumetric efficiency, and high temperature rating make it an ideal choice for applications requiring reliable performance and long life.
