Aluminum Electrolytic Capacitors are one of the most important components in many types of electronic devices. One of the more popular types of capacitors is the UPA1A821MPD, which has become a standard in many industries. This capacitor is a long life product featuring a low equivalent series resistance (ESR) and low leakage current. It is designed for use in low voltage and high current applications, such as adjustable power supplies, motor drives, power factor correction, and uninterruptible power supplies.The UPA1A821MPD is a polarized aluminum electrolytic capacitor capable of withstanding high temperature and shock. It is also highly resistant to temperature cycling, voltage surges, and a wide range of other environmental conditions. The capacitor was specifically designed to offer superior performance and long life in power applications. It is most often used in applications where the maximum ripple current is 150mA and the maximum operating temperature is 125ºC.The working principle of the UPA1A821MPD is similar to that of any other capacitor. When current is applied to the terminals, the electrical energy is stored in a field formed between two charged layers of material. The use of an electrolyte in combination with the aluminum plates increases the capacitance of the capacitor and thus improves its performance. The typical construction of the UPA1A821MPD consists of two aluminum foil electrodes that are separated by a very thin electrolyte. The aluminum electrodes are treated with an anodic film that provides a highly stable electrical barrier. This combination of features provides a device with superior electrical characteristics at high ripple current levels.In terms of application, the UPA1A821MPD is used for a variety of power management applications. It is ideal for use in applications such as DC-DC converters, switching voltage regulators, and LED lighting control power supplies. Its superior characteristics also make it well suited for applications in motor drives, robots, and HVAC systems. The extended temperature range and high ripple current capabilities makes it suitable for many harsh environment applications.In summary, the UPA1A821MPD is a long life aluminum electrolytic capacitor specifically designed to offer superior performance in power management applications. Its construction combines two aluminum foils electrodes, an electrolyte, and a highly stable anodic film. This combination makes it an ideal device for use in low voltage and high current applications, with excellent performance in terms of temperature cycling, voltage surges, and a wide range of other environmental conditions. It is also well suited for use in a variety of applications, including DC-DC converters, power factor correction, uninterruptible power supplies, and LED lighting control power supplies.
