How to determine capacitor values

2009-03-09 18:14:34

Been putting some guitar effects together
from mostly scavenged parts.
So far I can sort of ID the transistors, resistors are easy.
But damn those capacitor codes or what !!
And I've looked over a ton of sites via Google,
and I just can't seem to find a really good website that
has some pictures and text to help me.
The very little film caps have 104 on
them then the bigger ceramic caps
have 104 on them. I'm thinking that the ultra small film caps
that are maybe 1/16 of an inch in size would be pf.
So, I'm stumped !

Google again, "how to read capacitor values"

download a program called electronic assistant free from
www.electronics2000.co.uk. It will do the with ease

I agree, figuring out capacitor values sucks. In this case it is not
too bad though. 104 means 10 with 4 zeros after it; so 100000 pf, or
100 nF, or .1 uF, or .1 MF.

This is an easy one, but I don't know why in general, they had to make
it so &*()&*() complicated.

Maybe because they are trying to give the value of something that can
vary 12 orders of magnitude on something the size of a pebble.
