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.

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 ...

Capacitor Metals is gaining progress towards the potential mining of Tantalum and Niobium at the site of the Blue River ...

However, although the computer might have functioned even with the capacitor fitted the wrong way around, enthusiasts replacing it with a tantalum capacitor might find themselves in trouble.
