    When in doubt, look at the data sheet.

    There is an image of the cap, with a (-) sign next to the black 1/4 moon mark on the cap.

    Thanks

    Yeah, the datasheet tells it all. Apart of the black line (which is the negative side), you can see in the "outline drawing" which is the negative terminal.

    He's right the data sheet does say. Also the black line is the negative on every electrolytic capacitor I've ever seen.

    You guys are awesome, thanks!

    Also, a somewhat unrelated question: is super glue condutive? I just used a bunch of it to hold down a socket for a very simple hobby project, but the glue is connecting a couple of pins together...

    It is not conductive, but I have used it to hold smd devices down while soldering. When heated the supper glue burns off a bit. But some good PCB cleaner will remove it.

    Thanks

    Safety note: Super glue contains cyanide. Not at all healthy to inhale, especially as fumes while burning off a board. I don't have another suggestion about a glue to use, but super glue is a very bad idea.

    cyanide will just kill you before you notice the effects of the lead in the solder and the zinc chloride in the solder paste. :)

    You could use hot glue, its very useful. I've used it in many projects.
