Default parallel capacitors

Is it OK to parallel 2 600 VDC caps, I need 2.2uF 1200 VDC and really do not want to spend $43 a pop for 1200 VDC Mundorf SS caps.

Hi,
you need to add them together in series and use resistors to ensure equal sharing of the voltage.
I think using two 600V caps for 1200V is taking them too close to potential failure.

To get 2u2 1200V, you will need two 4u7 650V and that still leaves only a small margin for over voltage mains supply.
