FYI, OSCON SVPC 39uF 16v on my Mac mini now. BTW, not all Mac mini 2012 uses the Sanyo OSCON capacitors. On my Mac mini, it come with the following caps I believe it is the PXF series 39uF 16v caps made by Nippon Chemi-Con. And usually NCC uses marking ink with cyan color, so why it has black ink marking on Mac? I think it has the same reason - custom made for Apple. (Also, you won't be able to the same spec on NCC's catalog)
The capacitor is the OS-CON (solid polymer conductive) SVPC series 39uF 16v made by Sanyo (now merged by Panasonic). Usually the OS-CON capacitor has marking with purple ink colour. On the Mac, I think those were custom made for Apple, hence with black ink. I have the exactly the same Mac mini Late 2012 with i7 2.6GHz as well, and I use OSCON SVPC 39uF 16v to replace/fix the factory one.
