    viewsonic lcd monitor caps

    Will these do?

    1 x 2.2uf @ 50v 5x11 CapXon KF - Nichicon PS
    1 x 22uf @ 50v 6.3x11 CapXon KF - Panasonic FM

    I would use Panasonic FC for the 2.2uF 50V cap.

    and Panasonic FM for the 1000uF 10V

    Note: I have not done the usual esr and ripple comparisons while doing the above two suggestions.

      I just looked at datasheet again this time found ripple current
      470uf @ 25v 10x16 1010ma 0.076Ω CapXon KF 1790ma 0.026Ω Panasonic FM

      470uf @ 10v 8x11.5 550ma 0.150Ω CapXon KF 950ma 0.056Ω Panasonic FM

      1000uf @ 10v 10x16 1040ma 0.076Ω CapXon KF 2000ma 0.038Ω Rubycon ZLJ

      2.2uf @ 50v 5x11 55ma 2.80Ω CapXon KF 55ma 4.5Ω Nichicon PS

      22uf @ 50v 6.3x11 150ma 1.30Ω CapXon KF 406ma .13Ω Panasonic FM

        Nichicon PW 2.2uf 50V comes close at 55ma 3.0 ohms.

              Don't unbalance the pi filters... If you use caps with vastly differing ESR on the input/output of the coil, you will add ripple to the circuit...

              Post a photograph of the board indicating which caps are where.

They had double superiority in tanks and aircraft, triple in artillery, and in air defense and anti-tank weapons they had absolute supremacy. And what? Once again they were beaten. Once again they scrammed [sic]. Once again they screamed for us to come save them. Sadat woke me up in the middle of the night twice over the phone, 'Save me!' He demanded to send Soviet troops, and immediately! No! We are not going to fight for them."

                470uf @ 25v near transformer mosfets (bloated) no choke on this rail???
                470uf @ 25v at secondary output (bloated) no choke on this rail???
                470uf @ 10v after choke (bloated)for 5v rail
                1000uf @ 10v before choke 5v rail
                1000uf @ 10v before choke 5v rail
                2.2uf @ 50v across optocoupler led I think
                22uf @ 50v startup cap

                  Re: viewsonic lcd monitor caps

                  The ESR of the FM and ZLJ you picked are close enough it seems... Be aware when ordering Rubycon from Newark that often, the prices quoted are for multiples of many thousands and are not for sale individually or in small quantities. What is the model of your PSU? Maybe someone has already posted a pic.

                      If this is indeed the only pi filter, then this looks fine to me...
