What series of capacitors with a voltage of 35V and 50V / 63V is recommended use in switching power supplies?For values as from 1000uF?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Which role you are talking about?
And what do you recommend for larger currents , such as 10A and 20A?

Re: Capacitors for SPS
Sorry, forgot to mention that the capacity of filtering caps also depend on the frequency (on which the switchers are working).
So, it's not too easy to tell a value without knowing some information.
Usually, for 10A a value of 1000uF should be fine with most of the modern switching PS.
And because a PC PS used a 3300uF filtering cap for 30A, I suppose that for 20A you should be fine with a 2200uF.
