Default Post IDs of obscure polymer caps

The polymer section at http://capacitor.web.fc2.com/solidcapacitor.html is getting a bit long in the tooth now, so it would be good for members to post IDs for polymers they come across if they have the opportunity:

I'll start:


The brand is "Polycap", their website is http://www.polycap.cn.

Series in a nutshell:

RL - Ultra Low ESR
RG - Low ESR
RS - Higher voltage Low ESR
RN - Miniaturized for tighter fits
RF - Low ESR and 5000 hours

Please feel free to contribute and grow this thread if you have ID'd previously unknown polymer caps. Thanks.

Next we have "JB" Brand CS series caps. They are generic Chinese SMD electrolytic caps and not polymers, and they're found in Uniden phones (Good phones otherwise, they just need their caps swapped, unlike VTech which is garbage).



There is one lone cap in the cordless phone itself, and one or two in the corded base unit. The rest of the base unit electrolytics are all radial through-hole.

Up next is the Gemcon PM series polymer capacitor, with a 5000 hour endurance rating:





The capacitor looks ok on the inside, I would rate this brand as adequate.
