What does this symbol mean??

it's a capacitor with a rating of 100n. Most of the caps in this circuit have a measurement in n farads. I'm confused.

N = Micro if I remember correct.

You have a 100 micro fahrad capacitor.

Wouldn't n stand for nano farad?

It does indeed stand for nano. Thanks

Actually, it doesn't.

The first two digits, (10), are called "significant digits". The third digit is the multiplier. In this case, zero. The total is in picofarads. So, a 104 would be 10 with 4 zero's, or 100,000 picofarads, or .1 uf's. They don't rate caps in nanofarads.

The "n" is the tolerance. In this case, +/-0.05%.

So, you have a 10pf cap.

that's pretty crazy! Thanks for saving my butt!

That all depends on where you're looking at the numbers, but yeah, that's exactly it. If you're looking at a schematic that has the values written in nanofarads (and I've seen them, see runoffgroove.com), then the N does mean just that, nanofarads. Seeing that number on a cap itself would normally be the tolerance. A 100n on a schematic translates to .1uf just like your example.

Re: What does this symbol mean??

If there is no third digit it's just the first two numbers. Right?

So what's the deal?

You're right, and I forgot that he was looking at a schematic. I'm glad someone's looking over my shoulder.

Thanks, Erik.

I was just guessing, so when I post a question as a response, you shouldn't take my word for much.

They just choose to label the parts that way. Some label them in microfarads, some in nanofarads. In the case of what you're looking at, it's nanofarads. Just use a capacitor value conversion chart to get the microfarad number.

No problem, Artie. As soon as I saw he was talking about "n" in a value, I had a pretty good idea what he was looking at, and I guessed it right.

So a nano farad would be equalt to 1,000 pico-farads or .001 micr-farads?

Exactly.
