Aluminum electrolytic capacitors are a type of capacitor which uses an aluminum oxide layer as the dielectric material. This type of capacitor was invented by inventor Nikola Tesla in 1889 and first patented in 1896, and has since become one of the most popular types of capacitors due to its high capacitance values, relative low cost, and high breakdown voltage. The UPW2F100MPD1TD is an aluminum electrolytic capacitor manufactured by Panasonic Capacitor and optimized for use in high frequency, high temperature applications such as in motor drive circuits and switching power supplies. The UPW2F100MPD1TD aluminum electrolytic capacitor has a capacitance of 100μF and a maximum voltage rating of 40V, with a temperature range of -40°C to +105°C.

The working principle of an aluminum electrolytic capacitor is based on the same principles as any other type of capacitor, which is the ability to store and release electrical energy through two plates separated by a dielectric material. The main difference between aluminum electrolytic capacitors and other types of capacitors is the use of an electrolyte as the dielectric, and the use of an aluminum oxide film as the separator between the two plates. The electrolyte is usually made up of a combination of ethylene glycol, water, and acids, and the anode and cathode plates are usually made from aluminum foil. A small amount of current is required to polarize the anode and cathode plates due to the voltage-dependent capacitance, and this current is referred to as the leakage current. The leakage current is what gives aluminum electrolytic capacitors their higher capacitance values than other types of capacitors.

The UPW2F100MPD1TD aluminum electrolytic capacitor is most commonly used in motor control and switching power supplies applications due to its specific capacitance, high temperature and frequency rating. The ultra-low ESR (Equivalent Series Resistance) allows for smooth and accurate motor control and high-speed power switching, and the small size allows for easy installation in crowded PCB (Printed Circuit Board) boards. The capacitor also has a long shelf life, thanks to its low ESR, allowing the component to operate effectively for years. The UPW2F100MPD1TD aluminum electrolytic capacitor’s optimized parameters make it an ideal choice for a wide range of high frequency and high temperature applications, providing reliable and accurate operation for many years.
