We have recently had a rash of tantalum capacitor failures, where the
capacitors on an input filter fail to a high impedance state. These are
35V Kemet T491X series cap's, and the failure have been found at first
power up at 24 volts. Is there any known issues with these cap's? Are we
doing something wrong, like handling, design, other?

Thanks In Advance,
