Hi , I'm in need for some 10+ caps for my smps secondary side smoothing.
the thing is electrolytics are not cheap , so I need about 1000uF a piece but there is a big difference between whether it's 200v rated or 100v rated.
the voltage across the each cap would be about 92v DC , I wonder would a 100v rated cap be just fine in this application or do a higher voltage rating would ensure longer life , I mean how close to its rated voltage limit can a electrolytic capacitor work for long periods of time ?
thanks.
