Anyone read anywhere what the failure mechanism is for solid
dielectric caps of the tantalum variety ? In my experience, no matter
what the value, working voltage, or format (bead, bullet or box),
they always seem to fail leaky. Not open or short (well, very
occasionally short). Just leaky.

Hmmmm. They must have "improved" them. Recall all those gum-drop
tantalums in Tek scopes that failed dead short across the power rails?

Yes,I do,quite well. 8-)
