Anyone else rememenbr $\mu\mu$F (uuF) for
picofarad?
It's been a while, but yes, I've seen it.
Component labeling, what fun. I internalized resistor colour codes so
long ago it's impossible for me to (eg) see yellow-violet-orange and
not read it as 47K. (Fortunately manufacturers are sane enough that
Ditto. I do stil lahve to stop and think one some of the 4-bad (+tolerance)
E96 values, though.
Ther are at elast 2 ways that resisotrs can end up with 5 colour bands.
Either 2 digtis+multiplier + tolerance + something else (tempco?). Or 3
digits + multiplier + tolerance. At one point Maplin supplied a random
mix of resistors coded both ways....
20% resistors always have space for the not-there
fourth band, so it's
not ambiguous with 370K. Of course, 47K is a much more standard value
than 370K is, especially at 20%...but there probably exists a band set
If you have a 20% resisotr marked as 370k I want to see it!.
Nest we'll be going on about body-tip-spot coding...
that's a common value either way. Well, besides
palindromic labels
like brown-black-brown.)
Well, 27 is a prefered value although not in thr 20% series. So 270k
(red-violet-yellow) and 4k7 (yellow-violet-red) meet your requirements.
Now if I just had some clue about capacitor colour codes....
Err, yes.. The colurs are the same, but the order they appear in is
essentialyl random...
And I've seen small tubular inductors with3 coloured bands where the
multiplier is the middle band of the 3. Just to add to the amusement.
