< Hmm... If I'd seen that out of context, I'd have assumed it was 1000 < millifarads, not microfarads. Over here, we'd write that as "1000=B5F" That was the point. the user of uf instead of MFD was late '60s when I started noticing it. It's still sometimes used. < 1000mF =3D 1Farad :-) But I know what you mean. I used to have some ol < 50mfd 450V caps --and they were big, in those days. I still do. Actually part of the scaling things of capacitor values is related to the way they are used and the math for RF circuits. Also caps are generally two significant digits just like resistors and that is related to the common 20% tolerance applied to them (10% for resistors). I was more used to using number like 10^6 (megahertz) and 10^-12 pF from my RF days. < Err, I think there's an extra "0" in there somewhere, Allison :-) Damm, he lied. Actualy just a dumb typo. ;) Allison
