Okay. Question for the pros. Still getting my head around caps. Greenbean instructions say I need 100n film caps. Does that translate to 0.1uf? If so, for the 120n film cap do I translate that to 0.12uf? Because I've only got 0.1uf caps

The shortest answer I can give you to both questions is....yes.

However, I'm going to elaborate on it a bit, a 100nF cap is equivalent to a .1uF cap, and a 120nF cap is equivalent to a .12uF cap, now, if you have a circuit that you want to build that needs a .12uF cap, or a 120nF cap and you only have some .1uF or 100nF caps, you can quite easily substitute a .1uF/100nF for a .12uF/120nF and the circuit should still operate perfectly, you can also substitute a .15uF/150nF cap for the .12uF/120nF too with no problem, most electronic circuits are actually not that critical.


The only thing you need to be mindful of is that the DC working voltage of the substitute cap is equal to, or greater, than the DC working voltage of the originally specified cap, so say the circuit needs a .12uF/50V cap and you happen to have a .15uF/100V cap, it will be perfectly okay to use it as a substitute.
