   I haven't heard about that. Do you have a link to the write up? I did
hear about a lot of faulty caps due to a supplier that sold bad batch of
electrolyte to a lot of the cap manufacturers. What formula do you need
for caps? AFIK it's just a matter of buying them for the applicable
voltage. Yes there are formulas for capacitanace to achive the necesssary
filtering but the wrong results there won't cause them to burst.
