Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also called an aluminum electrolytic, is a type of capacitor that uses an aluminum anode, an electrolyte and a metal oxide cathode. It is a two-terminal passive electronic component with an anode and anode separators. The working principle of an aluminum electrolytic capacitor is based on Faraday’s Laws of Electrolysis. In this law, an electric current is passed through the electrolyte, which dissolves the anode material and deposits the metal oxide onto the cathode. This allows the capacitor’s current and voltage ratings to be increased.

One example of this type of capacitor is the UPM1K820MPD, which is an axial electrolytic capacitor with a maximum working voltage of 8V. It is available in three case sizes, with a tolerance of ±2%, and a capacitance range of 10µF – 680µF. This aluminum electrolytic capacitor is used primarily in general-purpose and uninterruptible power supply (UPS) applications, such as those found in computers and other electronic equipment.

As previously mentioned, the UPM1K820MPD aluminum electrolytic capacitor works on Faraday’s Laws of Electrolysis. This principle states that the electrolyte carries a current which causes a chemical reaction on the anode, creating a deposit of aluminum oxide on the cathode. This oxide layer allows electrons to tunnel through it, increasing the capacitance of the capacitor. Since this type of capacitor has a high capacitance, it can be used to store energy.

Due to its high capacitance and low leakage current, the UPM1K820MPD aluminum electrolytic capacitor is ideal for applications that require high voltage stability and high performance, such as power supplies, switching power converters, and output stage audio amplifiers. Because of its high operating voltage and capacitance, the UPM1K820MPD is also well suited for starting and running high current, high efficiency energy storage devices, such as battery-backed capacitors and flywheel energy storage systems.

The UPM1K820MPD aluminum electrolytic capacitor is a reliable and cost-effective choice for a variety of energy-related applications. Its low capacitance, high voltage, and low leakage current make it suitable for a wide range of power conversion and energy storage applications. With its superior features, the UPM1K820MPD can deliver satisfactory performance and reduce the production cost for many designs.
