I'm working on my first SMT board, trying hard to teach an old dog new tricks...
I have an 0805 10 uF electrolytic capacitor. As if 1206 isn't small enough for a beginner, but thats how this part came.
It is a small rectangle with a tin cap on each end to solder, and a dark band marking one end.
The data sheet, Here , (Mouser, AVX TACmicrochip Standard Microchip), has a nice diagram, clearly illustrating the polarity band, and that it is not to cross the center line for the part.
Only question is I don't see anywhere where it states that the polarity band marks the Positve or the Negative end of the cap.
