Where to find nanofarad capacitors in the US?

You should be able to get the 330 and the 100 from any of the major distributors. Not sure about the 120 though. Try places like

Oops, you're right - I goofed in my conversion. They're more common than I thought...

Its use is encouraged in order to avoid using the decimal point in component values. The idea is that photocopying cannot reliably reproduce a decimal point and also a speck of dust might look like a decimal point so it's best to avoid them.

Even so, you should be able to find nF values very easily.

p.s. values like 0.0047uF always drove me nuts. I never could be sure what size it was meant to be (it's 4.7nF or preferably 4n7), humans do not instinctively respond well to number values several zeroes beyond the decimal point. Research shows IIRC that we intuitively 'grasp' number values in the 1-1000 range best.

What drives me nuts is catalogs that express 0.1 uF as 100000 pF, with no commas for the thousands separator, and in small print. Counting teeny tiny zeroes all next to each other is a pain! There seems to be a real aversion, on the part of some people, to using nF.

best.

It's aeons since I saw that kind of thing. It's equally daft.

It's purely an American thing.

Compare with Farnell for example.

Easy. It's 4700 pF. ;-)

In that case, I'd look at the manufacturer's part number, or other order number - there's probably a "104" in it somewhere for an 0.1uF.

That is at least slightly more comprehensible but it get crazy when you get to
