Re: Capacitance HELP

while we are on the subject....

lets see if someone can explain the numeric code on very small ( 
physical size) caps....

for example  what is the value of a ceramic cap with     "560"  as 
the only marking on it    or  "100K   1KV"

good thing I have a cap meter  but having to test 30 caps to find the 
one I need is a pain...
some of the numerics dont even make sence to me from the meter reading test...
