Hi,
I'm building a high voltage output amplifier and thus require to generate positive and negative high voltage rails from a step up transformer feeds from 12V AC, as shown in the image. The high voltage amplifier output is about 6VA.
Normally I would have chosen smoothing capacitor rated for higher working voltage but due to size constraint, I have to choose between either 470u200V or 220u350V capacitors.
I know that rated capacitor voltages are working voltage(WV) but would a 200V capacitor suffice in this case?
Some capacitor data sheets did mention 200V WV and 250V surge but unfortunately the data sheet of the type of capacitor I'm using says nothing about surge voltage.
