Quick Capacitor Question

[frequencycentral]

The circuit I'm building (Tube Town Pepper Shredder) calls for some 22n / 0.022uf / 223 capacitors.

I don't have any, but I do have some 10n / 0.01uf / 103.

I just use two of these to make up the value? And does series or parallel make any difference?

Thanks!

Yep, you can use 2 of the 10nF caps to make up a 20nF cap - close enough!!
You place them in parallel....leg to leg so they make one big cap.
Caps in parallel add like resistors in series (C1+C2...), they are the opposite.

Resistors in parallel = R1*R2/R1+R2 and they add in series.

Thank, I just found some 22n / 0.022uf / 223 on an old board, so I'm sorted.

I find obselete electronics a great source of caps!

But thanks anyway, I was still wondering about that.

So is there any difference if one were to use caps in series instead of parallel?

Caps in series are just like resistors in parallel (as far as the capacitance value is concerned).

If you're lacking capacitors of a high enough voltage rating you can put a couple caps in series to compensate. So two 16V caps in series can effectively handle 32V - the voltages add. You don't see this much in effects, but it can be useful when building amps.
