Aluminum electrolytic capacitors, also known as aluminium electrolytic capacitors, are polarized capacitors, using a thin layer of aluminium oxide as their dielectric electrode material. They are one of the most widely used types of capacitors due to their high capacitance-to-volume ratio and low cost. The EET-HC2E681CA is an aluminum electrolytic capacitor with great features. It has a capacitance of 680 μF, voltage of 105 °C, and a high ripple current of 18 A.The EET-HC2E681CA capacitor is primarily used in DC link applications, such as DC/DC converters, in air conditioners or audio amplifiers. It also finds its applications in switching power supplies, elevators, home appliancs and other applications where high ripple current and high capacitance-to-volume ratio are important factors.The EET-HC2E681CA capacitor works on the principle of storing energy in an electrical field between two electrodes. When a voltage is applied across the capacitor, an electrical electric field is created which stores energy between the two electrodes. The rate at which the capacitor stores energy is determined by the capacitance of the capacitor, which is given in Farads. The voltage rating of the capacitor determines the maximum amount of voltage that can be applied across the capacitor.The EET-HC2E681CA capacitor has a dielectric layer of aluminium oxide between two aluminium electrodes. This thin layer of aluminium oxide is responsible for the electrical isolation between the two electrodes allowing them to hold the charge. The capacitance of the capacitor and its ability to store energy depends on the dielectric constant of the material and the physical size of the capacitor.The EET-HC2E681CA capacitor is a bulged aluminium electrolytic capacitor. It is designed to handle high ripple current while providing stable performance. The capacitor also provides excellent voltage support and temperature stability. The capacitor has a maximum operating temperature of 105 °C with a ±20% tolerance on the rated capacitance over the operating temperature range of -40 °C to +105 °C.In conclusion, the EET-HC2E681CA is an aluminium electrolytic capacitor designed for demanding applications requiring high ripple current and excellent temperature stability. It has a capacitance of 680 µF, voltage rating of 105 °C and high ripple current up to 18 A. The capacitor is primarily used in DC link applications, such as DC/DC converters, in air conditioners or audio amplifiers as well as switchmode power supplies, elevators and home appliances.
