I've been seeing some disturbing occurances re Tantalum capacitor (both
thru-hole and SMT). It seems that the reliability is not what I was hoping
for. (well, I was hoping for infinte life but ...)
Some have suggested replacing the Tant device with MLCC capacitors. I am
concerned that the reliability may be worse w ceramics.
If one goes into Mil-HDBK-217F, tantalum cap have a higher base reliability
then do ceramics. As long as the derating is below say 50%, then tant caps
((according to 217F)are more reliable then ceramics.
Any comments? Does someone have information that says ceramics are more
reliable? Tks
