David-
See also the technical report (available from AVX) "Surge in Solid
Tantalum Capacitors" by John Gill of AVX. He discusses the surge
failure mode of tantalum caps in low Z circuits (e.g. DC power
supplies).

Can anyone tell me if there are any drawbacks in using
tantalum capacitors in dc power supply filters? My recollection
is that they can "pop" if the voltage polarity is reversed, or if
there are large negative voltage swings during transients.
