    help identifying cap please...

    Searched all over for a suitable replacement with no luck, maybe I am doing something wrong, still not great at figuring the esr/ohm specs.

    Here are the specs:
    Teapo sc series 8mm x 11.5mm
    ripple = 580
    Imp. = 0.150
    From an hp mb

    cant find anything with a ripple close to 580? am I doing something wrong here?
    Thanks for any advice!

    Find one with higher ripple rating. Impedance/ESR has to be somewhat matched, but life of the cap can only improve if one with a higher ripple rating is installed.

      duh! I feel like an ass, I was thinking for some reason that the ripple has to be close to the same and esr could be higher.
      Thanks for pointing that out

        Voltage should be same or higher (unless you know for sure you can use lower), ripple same or higher, capacitance same (sometimes slightly higher is ok and ESR same (most times lower is ok). Can size depends on space available, use 105c over 85c and you are set.

          I have a bunch of these on hand:
          Rubycon 6.3v 820uf mcz

          would these work as a replacement?

            Is it no harm to replace with capacitor without ripple current rating?
            by chth96
            When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.


            Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
            But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.
            Rubycon YK DataSheet (b...

            What are typical ripple voltages on a laptop motherboard?
            by Antonynl
            I have here a HP pavilion hp 15-cs2975nd with a 1.095v power supply that is driven by a FDMF3035. I do see about 80mV of ripple on my scope. I searched through the datasheet to find possible values of the ripple but I don't understand the datasheet well enough.

            So I have two questions:
            1) what is the typical ripple voltages of gpu/cpu on a laptop or pc mobo?
            2) what would be the max ripple of a FDMF3035 that drives an output of 1.095V?

            Would be nice to have a rule of thumb of say a percentage of the supply voltage to be an acceptable ripple voltage....

            Can't find exact matching caps for replacements, what should I get to prevent video issues?
            by SluggerB
            I have an old Tivo. The Power Supplies are known to have caps that fail. Here are the caps that come with the original power supply:



            I could not find replacement caps with the exact same specs. I followed an online guide and recapped the power supply with caps with these specs



            The power supply now works, however the HDMI video is giving me eye strain. I don't know how a capacitor on a Power supply could impact an HDMI video signal, but it does, the Tivo interface has a flicker now and the color/brightness is off. So I want to get some new caps...

            Is there a manufacturers tolerance for ripple?
            by Ady2017
            Hi all

            I need to replace a 680uF 35V SamYoung NXB cap which has got a ripple of 1820. Whilst passing my local little electronics shop I picked up what they had in stock which was a 680uF 35V Panasonic FC with a ripple of 1655.

            As the ripple rating is only 9% below what the original was I am wondering whether to risk it and fit it.

            The catalogues specify a capacitance tolerance of +/-20% but state nothing about the ripple. If there is a similar tolerance for ripple then I might be worrying about nothing. Does anybody know?

            Thanks

            Genelec 8020C Bad capacitor
            by TomGJ
            Hi All, So I have two Genelec 8020Cs that are about 10 years old, one of them stopped switching on. I took it apart, fuse was blown, and I've traced the short to one of the two large capacitors on the circuit board.

            Now from looking at the Capacitors, they seem to be from Samwha's SD Series with the following specs: 3300uf, 35v, 85C, 25 x 16 mm Radial.

            The problem is, I can't find any capacitor from Samwha's SD Datasheet that matches these specs. The closest is 3300uf, 35v, 85c but 31.5 x 16mm, with a max ripple current of 2.5A. I'm guessing the 25mm is custom made for...
