Tantalum capacitor - Wikipedia

Tantalum capacitors are manufactured from a powder of relatively pure elemental tantalum metal. A common figure of merit for comparing volumetric efficiencyof powders is expressed in capacitance (C, usually in μF) times volts (V) per gram (g). Since the mid-1980s, manufactured tantalum powders have exhibited around a ten-fold improvement in CV/g values (from approximately 20k to 200k). The typical particle size is between 2 and 10 μm. Figure 1 shows powders of successively finer grain, resulting in g

Sep 10, 2016  Re: Repair/Restoration of Vintage Computer devices with Tantalum Capacitors. « Reply #1 on: September 09, 2016, 08:33:19 pm ». Tantalum capacitors are "self healing", meaning that they regrow the barrier layer if there is a crack in it. The problem is that this healing process releases oxygen and heat, which in large amounts can allow combustion.
