Competition for tantalum metal by industry can be intense because of its narrow supply chain. Of the 5.5 million pounds consumed in 2021, about …

About Tantalum Capacitors. A Tantalum Capacitor is a type of electrolytic capacitor, made from tantalum metal. The tantalum metal is used as a polarized anode to store energy at a high capacitance, relative to its small size. Uses for Tantalum Capacitors include power supply filters for motherboards, laptops, cell phones, and more.

Kemet Electronics Corporation Abstract The capacitance range for tantalum capacitors spans from singular microfarads (uFd) through a thousand microfarads. It is an electrolytic type of capacitor that can utilize either a liquid type of electrolyte or a solid state material as the cathode connection.

For example, today's tantalum capacitors are able to offer up to 22µF at 4V in the 0402 case size. At the other end of the voltage range, one can find tantalum capacitors of up to 47µF at 50V in a single package, and even higher in through-hole packaging. Conventional tantalum capacitors utilize manganese dioxide (MnO 2) as the …

A solid tantalum capacitor consists of a sintered anode with an oxide formed throughout its body, creating tantalum pentoxide as the dielectric. Then, a magnesium dioxide (MnO2) or polymer system is applied to form the cathode. The formation of the anode slug for a wet tantalum capacitor is done in much the same way as the solid tantalum capacitor.
