    Challenge! Can you help me identify these parts?

    Greetings, I'm hoping some can tell what the items in this picture are: http://screencast.com/t/LR0V5eXs

    I have one that looks just like the pic labeled "470" instead of 220, and the small text reads "835f d". It broke off the mobo and I need to get another.I know that sound weird, but it's true. The contacts broke right off at the body.

    I think its a polarized capacitor of some kind and they seem to be a rather common component, but I've looked for hours and just cannot figure it out.

    If you know where I might get another or what I could replace it with, that would be great!

    Thanks!

    They're Tantalum capacitors. 220 mF.

      Wow good eye tantalum caps at 220 μF crazy what gave it away the package is not as noticeable to me I guess being non EE just a tinkerer did you look up the 60LH @ 220 to find your answer or were you just familiar with the package?

        Thanks!

        So can I assume that a 470 marking = 470mF? How does that convert to pF or uF?

        Any idea what the voltage might be?

        Please pardon my ignorance...

          depends on what you are talking about and what circuit it is in for instance an inverter for a ccfl backlight would likely mean 470volts rather interesting I guess you need to know the circuit and the component in order to determine what these numbers designate in that fashion there is no simpler way that I am aware of to know what they designate.

          Sometimes the number on the component you can look up and get your answers after some brief searching other times it takes you lots of comparison and knowing what the mounting styles are TSOP SMT BGA so on so forth.

          Enjoy maybe this helps and maybe there is an easier way to come up with the numbers but I can't think of one myself.

            Normally, it would be 2.5v (the "e" after the date markings). 220 mF 2.5v.
            But markings vary according to the manufacturers, it'd be safer if you provide the brand and model of whatever you're trying to fix.

              Finally found it! If you want to know, it's this one:

              Thanks for your help! You got me going in the right direction.

                This link to replacement capacitor is not what you want due to gerneral purpose term.

                And this is not a Tantalum and OP wanted 470uF not 220, please read carefully.
                This is actually polymer SMD capacitor due to low profile than tantalum. Pick up a junk notebook and salvage one.
