For tantalum caps, here's one vendor's (AVX Corp.) suggestions for
surge failure prevention (I haven't read either very thoroughly, both
contain bibliographies pointing to lots of related material); all articles
are in Adobe PDF format:

o "Increasing Reliability of SMD Tantalum Capacitors in Low
Impedance Applications", D. Mattingly

http://www.avxcorp.com/tech/techpdf/rel_ti.pdf

o "Surge in Solid Tantalum Capacitors", J. Gill

http://www.avxcorp.com/tech/techpdf/solid_ti.pdf

Also, they have a number of decoupling-related technical
articles related to decoupling (quality varies); see

http://www.avxcorp.com/tech/library.htm

for the index.
