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

coplanar parts like tantalum capacitors but is a major factor with non-coplanar parts like integrated circuits (ICs). Thicker solder paste laydown is needed to fill gaps that are left when the IC leads are not in the same plane, minimizing missing solder joints on those devices. Solder surface tension is the defect
Introduction: Specifics of Polymer Tantalum Capacitors, Cont'd Wear-out failures. Paulsen [12] observed wear-out failures in polymer tantalum capacitors and demonstrated the applicability of the Prokopowicz and Vaskas model for accelerated testing of these parts. Experiments show that the exponent n ranged from 10.5 to 19. The E
1. For LEDs, diodes, tantalum capacitors, and so on, polarity means the active/negative electrode of the component is in the same direction as the PCB's active/negative electrode mark. 2. For ICs (including BGAs), and multi-pin inductors, polarity means the component's first pin/ball is in the same direction as the PCB's first-pin mark.

The Kemet T350E106K016AT is a 10 µF, 10%, 16 volt, radial lead tantalum capacitor. It offers the advantages of small size, low leakage, and low dissipation factor for filtering, bypass, AC coupling, and timing applications. The final electrolytic capacitor type is the niobium oxide electrolytic.
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.
The first solid Tantalum capacitors with a tantalum powder anode sintered in vacuum, an anodic oxide film of tantalum as the dielectric and a manganese dioxide (MnO 2) cathode were invented in the early 1950 s at the Bell Telephone Laboratories in the USA. 1 Similar to the liquid electrolyte cathodes in Wet Tantalum capacitors developed …
