but are generally unsuited to AC power applications due to their necessary polarity, but they are very frequently used in DC power supplies. When compared to aluminum electrolytic devices, tantalum ...

A capacitor made out of the precious metal tantalum. The silver-gray tantalum beads, in the form of compacted powder, can store a lot of charge relative to their mass. This enables smaller ...

The pioneering years in the history of capacitors was a time when capacitors were used primarily for gaining an early understanding of electricity, predating the discovery even of the electron.
