I'm a bit unclear on what capacitor should be used in terms of voltage rating.
On a previous post I read it was safe to run 32VDC on a capacitor rated @ 35VDC.
My understanding and from what others say - a 20% safety margin was the norm? My current project ; Pass's Balance Line Stage quotes "Substitute capacitors should have a 100+ volt rating". The power supply voltage it uses is 80V and after regulation it drops to around 60V. So why spend the extra $ when a 63V cap will do in the 60V circuit?
I know electrolytic capacitors can have a tolerance deviation of +/- 20% That is a huge variance and what does the tolerance imply if running capacitors at near 100% rated voltage level? I know capacitors explode like a bomb when exceeding their rated voltage. But I also have seen them explode within normal voltage range.
