    While trying to repair an LCD monitor, I have accidentally ripped the
    following capacitor off the circuit board. Here is a rough drawing of

    It is a small silver round cap, with two leads and a rubber insulator
    underneat. Clearly it's a 25V capacitor... can anyone tell from the
    marking what the value of the capacitance is?

  2. 100 uF surface mount.

    100 uF / 25V !

    Make sure you didn't roip the pcb pads off btw. it's quite likely you may have !
    In which case you're going to have to improvise a repair.

    Thanks guys! I didn't rip the pads off. Anything wrong with replacing
    this with a 100 uF electrolytic?

    It *is* a 100uF electrolytic ! A leaded type may be a bit bigger though.

    Thanks! That's what I thought, but wanted to be sure. (I'm enough of
    a noob to not know this, but I have enough experience to be dangerous
    to myself :p)

    Sorry it wasn't more obvious but I assumed you'd realise by the size of the
    part. SMD electrolyyics look a bit different to their leaded cousins.

    In case it's not obvious - you have to get the
    polarity right.

    That much I know! I know about electrolytics, just not the
    surface-mount variety. Thanks guys.
