Aluminum electrolytic capacitors are electrical components used in a variety of electronic circuits. They are used for a variety of functions, such as to store and release energy, to act as a filter or to act as a timing device. They are usually the case of choosing capacitors that are of high quality and that can be used in a variety of environments. The UCY2V390MHD aluminum electrolytic capacitors are one of the most popular and reliable components for these applications, thanks to their low internal resistance and capacitance, excellent temperature stability and their wide range of operating temperatures.The UCY2V390MHD is a low-impedance, aluminium-polymer, electrolytic capacitor. It features a capacitance range of 2.2 to 3900 µF, with a voltage rating of 16VDC, an operating temperature range of -40°C to +105°C, and a maximum ripple current of 800mA. The aluminium-polymer construction gives this capacitor a combination of high capacitance to volume ratio and very low ESR, making it suitable for a wide range of applications including filters, rectifiers, inverters, and DC protection circuits.The unique structure of the UCY2V390MHD also makes it ideal for applications requiring very high capacitance and very low internal resistance, such as those in power supplies and switching regulators. It has a low ESR, an extremely low loss factor, and an excellent frequency characteristic, providing much higher power output. Additionally, it is highly resistant to voltage, temperature and humidity variations, and shock and vibration.The working principle of the UCY2V390MHD is based on the same principles as other types of electrolytic capacitors. Electrolytic capacitors are constructed of two metal plates separated by an ion-containing electrolyte. The plates act as two conductors, with one plate being an anode and the other a cathode. When a voltage source is applied across the plates, the electrostatic field created by the electrical charge causes ions to migrate between the two plates, creating a deposit of electrons which form a resistance that acts as a capacitor. This is the same working principle used by all types of electrolytic capacitors.In the case of the UCY2V390MHD, the metal plates are wrapped in a polymer that prevents the electrolyte from leaking out. This provides greater reliability and also significantly increases the capacitor\'s lifespan. The polymer also acts as an insulator, which prevents any damage to the capacitor caused by electric arcing and shorting. In addition, the low ESR and low loss factor of the UCY2V390MHD increase its efficiency, allowing it to handle higher currents than other capacitors.The UCY2V390MHD is most often used in power supplies, DC protection circuits, and other power regulator circuits that require high capacitance and low internal resistance. It is also suitable for filter circuits, rectifier circuits, and inverters due to its high temperature stability, wide operating temperature range, and low ESR. Additionally, its high capacitance to volume ratio makes it ideal for a wide range of applications, and its low ripple current makes it suitable for applications that require low ripple current.Overall, the UCY2V390MHD aluminum electrolytic capacitor is an ideal choice for a wide range of applications. Its low internal resistance and capacitance, excellent temperature stability, and wide range of operating temperatures make it suitable for everything from DC protection circuits and power supplies to filters and inverters. Its polymer construction provides greater reliability and increased lifespan, and its low ESR and low loss factor make it highly efficient.
