Electrolytic voltage rating in dac

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

There are many 100uf and 10uf caps rated 50v and 63v in a dac with a 12v regulated supply. The most I see without measuring everything is 24v across an op amp. I see no reason to use anything above 25v or maybe 35v. Why would the manufacturer use such high voltage caps?? Is my assumption that 25V is all I need correct? A couple of measurements of cap voltages were way low. Would this be for longer life or maybe they just got a good deal on cheap caps? Thanks, Tweaker
