    This fell off a remake motor controller board (found in NGG, TZ, etc.). It's a cap according to the printed board. I did not receive schematics for this nor do I know who made it. Anyone have schematics or know a way for me to ID and replace this cap? Can I just throw any 100u (50v?) electrolytic cap on there?

    Quoted from DANGERTERROR:

    Not quite. It's a SMD component, not a through-hole component.

    BEAHAHAHAHAAAA

    Don't worry I just did this to see if I could.

    Yeah I just need to sort out the value then and order.

    Or if anyone knows how to contact the mfctr?

    If its the same SMD as on the board, and there is no damage to the pad, it looks like you can solder it as the pad protrudes outside of the package. With care...and some careful tinning.

    If the cap is still good and your rig works, why not solder it back on. You already have a nice blob on the board.
    All it has to do is stick to the pads. I have done it many times.

    Looks like there is through holes too... Desolder them clean and you can stuff a leaded electro cap.

    I got it back on. There just isn't much lead to work with. Should probably do this the right(er) way...

    Anyone know why the cap doesn't have its value on it? I'm not sure what 100 50A. means?

    It's a 100uF/50V.
