Among 0805's I've got on hand in the 1 to 10 ohm range,
x.x seems to be a little more common than xRx, but both
occur repeatedly. Eg, 1.1, 2R7, 3.3, etc. Besides those,
I haven't seen any 5% SMD resistors or data sheets with
direct values.
For resistors under 10 ohms, yes. Nothing above that?
I ask because I've been analyzing my technician's washing-
machine VFD motor-control circuit board. This has an 0805
resistor labeled 120, which must be near 120 ohms, because
if it was 12 ohms the circuit not only wouldn't work, it'd
go up in smoke. Actually, it did go up in smoke, burning
out the "120" resistor (and many other components), so I
can't measure it. The circuit board has mostly US-made or
familiar parts, but also a few foreign-looking parts. The
other 0805 resistors have conventional labeling, a 33-ohm
part says 330. But this 120 fellow simply can't be 12 ohms!
Further complicating the issue is that this 120 resistor was
thrown away when my technician replaced it, but both he and I
clearly remember it said 120, I had even written it down. To
my memory it looked just like the others. But hey, it really
couldn't have been 12 ohms! :-<>
