Tantalum capacitor scrap

CCRcameron, By looking at the pic, (last one) I'd say those are what I call can capacitors or electrolytic caps. The negative marks is the tattletale. "Thank you Wiki"

Try a little "demolition test" on #7 & #9 and for that matter any you question on them being Tantalum cap. If you take a large pair of channel locks and squeeze the cap and it easily makes a impression or dent, more than likely not Tantalum. This info I learned from reading the old post of a long time member who knows a thing or two about Tantalum caps. Also with these caps try your magnet, all of the tantalum caps I have found have magnetic properties. So do a lot of the leads on a lot of other caps. As Mechanic said most, if not all of these look like electrolytic caps. The man that runs this thread will have to tell yes or no on the specifics of what he buys.One thing I should clarify, use the "channel lock test" only on the metal caps, if you do that on the epoxy/plastic one your only going to make a mess!

I could not of said it better myself - If you try the "Demolition Test" and it bends or pops open then it is 99% an Aluminum Electrlytic Capacitor.

All Tantalum capacitors have a magnetic strip in between the Tantalum and the capacitance charge - That is correct.
