Filter Capacitor & correct voltage

jomatecc · 27th October 2008, 10:49 AM

This is a question that has been bugging me for a while now,hope someone can clear it up for me, I've purchase a bank of 4700uf 100v Nichicon Muse from ebay want to use them in a PSU where the tranformer secondary would be 22-0-22 AC, almost 35v-0-35v DC would on the filter caps.
My concern is that using the caps at this low voltage might impact negatively on subjective sound quality, as opposed to using them with voltage closer to their 100v rating. If anyone has experience and/or knowledge with this your feedback will be greatly appreciated, thanks in advance.
regards

Hi,

They will have no effect on sound quality, they are simply
physically bigger than they need to be, i.e. same size 50V
would have a higher capacitance value.

Thanks a lot sreten, as long as there isnt any performance hit Im ok with the size. Regards.

probably will get a better life out them then one with a lower voltage.
