Explaining Capacitors and the Different Types | DigiKey

Whereas the rule of thumb for designing with Ta/MnO 2 capacitors is to de-rate voltage by 50% (or more if series resistance is very low), the leading manufacturer of NbO-based devices (AVX) has suggested that de-rating voltage by only 20% is sufficient for safe operation. Additional de-rating beyond these levels can improve long-term reliability of both device types
