Usage of Tantalum vs Electrolytic Capacitors : r/AskElectronics
"Dry" tantalum caps are less sensitive to heat as they have no liquid that could dry out. On the other hand, they are much more sensitive to overvoltage as local internal shorts make them fail catastrophically, while aluminium caps can take some blows before they fail. Tantalum caps are smaller for the same capitance and voltage.
