Are tantalum capacitors safe for use in new designs?
Wikipedia - tantalum capacitors. Most tantalum capacitors are polarized devices, with distinctly marked positive and negative terminals. When subjected to reversed polarity (even briefly), the capacitor depolarizes and the dielectric oxide layer breaks down, which can cause it to fail even when later operated with correct polarity.

Should I Use a Tantalum or Class II MLC Capacitor in My Circuit?
However, one big benefit of tantalum capacitors is that these capacitors can handle capacitance values up to 1,000 µf, which is 10X greater than the maximum capacitance value of a Class II MLCC. This makes tantalum capacitors a good fit for applications that need quick bursts of high capacitance and charge in a small package …
