Note that tantalum pentoxide has a dielectric constant of 26, some three times greater than that of aluminum oxide. This, in addition to the fact that extremely thin films can be deposited during the electrolytic process mentioned earlier, makes the tantalum capacitor extremely efficient with ...
When pure, it is ductile and can be drawn into fine wire, which is used as a filament for evaporating metals such as aluminum. Tantalum is almost completely immune to chemical attack at temperatures below 150°C, and is attacked only by hydrofluoric acid, acidic solutions containing the ...
Tantalum capacitors: use metal tantalum as the medium, unlike ordinary electrolytic capacitors that use electrolyte, tantalum capacitors do not need to be wound with aluminum-coated capacitor paper like ordinary electrolytic capacitors, and have almost no inductance themselves, but this also limits ...

Thus, comparing the two basic types of tantalum powders when used for capacitor manufacture shows that the sodium-reduced powder material has a higher capacitance per gram of powder and better green strength for pressed compacts, while electron beam melted, degassed hydride powder material has higher...
reliability of these capacitor types can be illustrated with the familiar bathtub curve, which shows an eventual increase in failure rate as the cathode system degrades. Tantalum capacitors with conductive polymer cathodes and aluminum capacitors with wet electrolytic systems exhibit this wear out ...
