Aluminum Electrolytic Capacitors are widely used in many applications because of their low cost, high capacitances, high currents, and long life. The UPJ1K820MHD6TO is one such capacitor, designed for high-temperature operation and long service life. It has a maximum temperature range of -55°C to +125°C, and offers a variety of abilities to fit the needs of many applications.

The UPJ1K820MHD6TO’s capacitance ranges from 1.0µF to 820µF, with a rated voltage of 10-450VDC, and leakage current of 0.05CV or 3µA whichever is greater. In addition, it is rated for 400,000 hours of lifetime at +105°C, and offers a low ESR that guarantees the part will be reliable. This makes it suitable for several applications, including audio, communications, computers, consumer electronics, and other fields where miniaturization and power density are desired.

The working principle behind the UPJ1K820MHD6TO is that of an electrolytic capacitor, which utilizes an electrochemical reaction to create energy storage. A positive and negative plate are constructed from aluminum foil separated by a layer of an electrolyte, usually a form of liquid. When the capacitor is charged, the positive and negative plates store their respective electric charges. These charges then neutralize when the external voltage is removed. The dielectric property of the electrolyte stabilizes the electric field, meaning that the electric charges will remain stored until needed.

The electrolyte also functions as a conductor between both halves of the capacitor, leading to low ESR, or equivalent series resistance. This further allows for superior charge/discharge characteristics and higher ripple currents, two features that make the UPJ1K820MHD6TO an effectively small-sized power source ideal for many different applications. Additionally, the capacitor comes in various types of shells and case sizes, allowing for better installation and flexibility.

The UPJ1K820MHD6TO is an exemplary aluminum electrolytic capacitor, with a wide variety of potential applications and the capability for power density and miniaturization. Its low-ESR, high capacitance, and long life make it an ideal choice for many different electronics, audio, computer, and communications applications. Its special construction and specific capacitance, rated voltage, and temperature range allow it to handle many different applications.
