    Seeking "Ripple Current Confusion" paper by Kemet

    Hey everybody.

    Trying to understand the meaning of ripple-current specs for capacitors, I've seen references to a paper apparently entitled "Ripple Current Confusion", by Kemet. I've found that the links to the paper are broken, and that it doesn't seem to be on Kemet's site.

    Can you post that paper or a good link to it?

    Thanks.

      url works for me

      Ripple current is mainly about heat and the cap dissipating it while also having a long life. Cornell Dubilier has some better tech papers I recall.

          Yeah, hmm, that works for me now. Thank you.

                  Sensor on Aurora AS1018CD paper shredder doesn't work
                  by CapSnap123
                  I'm getting frustrated troubleshooting a paper shredder. The way the shredder normally works is when you turn the power on, nothing happens until you insert a piece of paper. There is an IR shredder in the shredder and inserting the paper breaks the beam and starts the shredder motor. But now the motor runs constantly, even when no paper is inserted. I've replaced the photodiode and the IR emitter. Also the relay makes a nice clicking sound so I assume it is working too. I don't know what else to check. Here's a photo of the circuit board. The red and black wires marked IR - go to the...

                  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....

                  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
