Hi, confusing isn't it. well the numerical marking take a 1 uf cap might be labeled 105 and 104 is .1 and 103 is .01 and 102 is .001 472 would be .0047 and 475 would be 4.7 uf.. hope you get where i am at. cul brian f.

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...

A little off the subject, I use a French (azerty) keyboard, and it has a key for "mu." I'll put ot on the next line to see if it reproduces as mu on your screen: 


_________               µ  _______________
I got to wondering if you could use alt +asci number to reproduce the Greek letters. 

        I'll use alt + 230 (mu) to see what happens:

____________    µ ________

        I suppose it's more trouble than it's worth.

        I also have  the square symbol:

                ________² ___________

        That's alt+253
