MOTM

>>The MOTM choice is a .01uF axial cap.

Errr...nope. The caps that I use a re 0.1uf (marked 104). Look at ANY MOTM documentation or
schematic.

Doh!!  I should have caught that.

Does anyone else think that 100nF reads better??

So far,  I have not seen caps *marked* in nF.

The whole \ufffdF, nF, pF thing is really confusing to begginners.

All of the "yellow box" caps in MOTM are marked in nf. It seems to be "popular" for film caps
between 1000pf and 0.47uf.

I've seen caps with "n", like those yellow box caps.

Don't forget "MFD" and "mmF" :)  That it jumps every three zeros 
seems intuitive enough, but it isn't used consistently.  For some 
inexplicable reason,  engineers don't like nanofarads.  You never see 
a 100 Ohm resistor called .1K

>So far,  I have not seen caps *marked* in nF.

In the UK, and probably the rest of Europe. Polyester box caps, and the
larger polypropylene types are all marked in nF. You will see values
like 680n, 10n and so on.

Many engineers refer to uF as 'muff' and pF as 'puff'. Poor old nF just
gets called 'enn'.

An old circuit simulator I used would measure resistance in K. Thus 0.1K
was the only valid form of 100R. It was pretty stupid in many other ways
too. Like the op-amp that would always rail out at +/-12V, even if the
supply voltage was +/-6V!

OOOPS!!!
Sorry, I was going by memory.  Obviously old age is setting in.

Actually, I found it got easier when I encountered nF.  Converting directly
between uF and pF was always a confusing hassle (what's 0.001uF again?);
having nF in the middle really helped the brain, just like ohms, K, and M
for resistors.  If I never saw numbers bigger than 1000 or smaller than 1 on
a schematic or parts list, I would be very happy.
