Has any one had any problems with Vishay Capacitor P/N 595D226X9050R2T failing?
From our electrical engineers statement the most common failure is during
in-circuit test.  This is conducted at ambient temperature & humidity.  These
capacitors are used to decouple an input voltage, which is set to increasing
values.  The failures have been occurring when a steady-state input voltage of
around 38 VDC is used.  When the voltage is left on, the chances of failure
increases.  For example, two different capacitors were blown when the input
voltage was left on for about 2 minutes.
