    Capacitors for SPS

    What series of capacitors with a voltage of 35V and 50V / 63V is recommended use in switching power supplies?For values as from 1000uF?

    A power supply uses many caps in different roles. A cap used for filtering is not the same as a startup cap for example. Or a cap filtering 20amps is not the same as a cap filtering 500miliamps.
    Which role you are talking about?

      I like nichion pw for smps in those volts.

          It is to source with output amperage between 2A and 5A.
          And what do you recommend for larger currents , such as 10A and 20A?

            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.
