The caps in the photo really are NOT solid polymer caps.


Ok, I stand corrected.

They're regular Sacon brand conventional wet electrolytics, only
housed in the same kind of packaging normally used for polymer caps.


Groan. So much for my method of using the case style to recognize the
difference between electrolytic types.

Even some of the replies in the message thread where that photo is
from mention this. Real polymer caps, except Fujitsu hybrids, don't
have explosion rupture cutouts, unlike the caps in the photo -- notice
the "K" rupture cutout on top of each cap.


So that's the trick to recognizing the difference. Thanks.
