how do i create a .012 capacitor?

When you connecting capacitors in parallel the values add up (like connecting resistors in series).
C = C1 + C2

When you connect them in series you get the same thing as if you were to connect resistors in parallel
1/C = 1/C1 + 1/C2

place two 0.022 in series and you'll be in the ballpark, within tolerance

ok, thatll work...how about .09?

connecting a 1uf and a 0.1uF in series is close (but that 1uF may be pretty big...). Connecting 2 0.047uF in parallel is pretty close.

PERFECT!!!

how about a .010?

im getting really close to a specific tone...

Seljer · July 11, 2006, 02:06:03 PM

0.010 is a pretty standard value that should be available

i cant seem to find it anywhere. ill keep looking.

You're probably looking for a 0.010uf instead of a .01uf cap. Look for a .01uf.

These are very common and even *gasp* Radio Shack should have them.

the rat shack in my part of town went under. they were down the street, too.

Also, don't forget that .010 uF is the same as 10nF

That depends on what material caps you are using. For polystyrene you can get a .01uf and a .002 uf to make .012uf. For polypropylene and certain film caps you would have to use a .01uf and (2) .001uf's. This is probably for the sweep cap in a wah right?
