tantalum capacitors with manganese oxide cathodes these failures result not only in a short circuit in the system, but can also cause ignition due to the exothermic reaction of tantalum with oxygen generated by the overheated MnO2 cathode layer. Examples of tantalum capacitors burnt after surge current testing are shown in Fig.1. Fig.1.

Capacitors consist of two conducting surfaces, usually metal plates, whose function is to conduct electricity. They are separated by an insulating material or dielectric. The dielectric used in all tantalum electrolytic capacitors is tantalum pentoxide. Tantalum pentoxide compound possesses high-dielectric strength and a high-dielectric constant.

2. The Polarity of Tantalum Capacitors. A typical tantalum capacitor is polarized and has positive and negative poles. The component is usually yellow colored and is designed to be surface mounted on the circuit board. On the surface of the housing, an end marked in-dash denotes the positive pole, and hence the negative pole is at the …

In the tantalum electrolytic capacitor, the distance between the plates is very small since it is only the thickness of the tantalum pentoxide film. As the dielectric constant of the tantalum pentoxide is high, the capacitance of a tantalum capacitor is high if the area of the plates is large: where C = capacitance e = dielectric constant

If the capacitors are not properly derated, they simply need to be replaced by components that are derated. So for a 15 volt power rail a 100 uF should be replaced by a 100 uF, 35 volt tantalum. It is hard for me to imagine replacing with an electrolytic cap as these have clearly stated, relatively short lifetimes.
