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
