[Amps] TL-922 question

In my experiences, they don't open, they short because the dielectric  
punches through.<
I have had two ceramic tx caps go open - the voltage rating was OK, but the things heated up and burnt the silvering away without apparently punching through. That wasn't on a TL922 though, and mostly, the failures I've seen have been dielectric failures as Rich says. But not invariably.
