CK2III build question: Polarity of caps.

[tintin47]

For the CK2III, I am attempting to begin soldering the 10uF 50V bi-polar aluminum Electrolytic capacitors, and I can't find any info on polarity. The PCB has a clearly marked + on one of the printed holes, so it seems that they should be polar, but there is no info under the part data sheet or on the part itself. (Mouser part
# 647-UVP1H100MED if anyone wants to look at the data sheet for themeselves) Thanks for any help.

Bipolar means that the cap itself is not polarized, so you can put it either way.
Personally I use the longer lead for the positive hole even with bipolar caps as I like to keep things consistent.
However, as far as I know the Nichicon PV caps are all polar. On top of that the part number you gave is not correct.

Thanks. I don't think that it is a PV cap, being as I switched the V and the P when typing. Sorry for the confusion. The real part number is in the OP now.
