Hi, Group!

We all know that the little black paint on the top edge of  a ceramic disk
cap means "NPO".

Does anyone know what a dark purple on a sorta gray body means.  What
temperature coefficient does a purple paint stripe at the top of the cap
mean?  I swear I once new................

Anyone remember what those paint marks at the top of the caps mean?  I
placed the capacitor in my c-meter and heated it up with a soldering iron.
The capacitor got pretty hot but didn't change value much.  Is this purple
mark another version for NPO?

Thanks,

Bill
