Hi Phil,

I'm no component expert, I just have some time on my hands at the moment. Check this link out, pretty nice one that explains the EIA codes:

Subject: [TN] capacitor temp coefficient 

Ok, for you component experts here is my question.

For ceramic capacitors there are many temperature coefficients.  In comparing data sheets from different manufacturers I find both COG ( C-Oh-G) and C0G (C-Zero-G)  [alternatively NPO and NP0].  I was under the impression that C-Zero-G was the original and correct identification.

Any comments?
