0 (ZERO) Ohm Resistors (WTF)........

Guest
There are some sellers on ebay who are selling assorted resistors in
quantity. Some of them claim these assortments contain 0 ohm
resistors.... WTF. Wouldn't that be a piece of wire?

What would be the point of that?

How would you even color code it?
 
Also designed for component insertion machines which can't really handle bare wire.

Can be used as "ID" links to enable/disable features on different runs
of a board.

used as jumpers when you don't have enough pcb layers.

[about zero-ohm resistors]

Now, assuming they use a color code on them, what would it be?
I thought it would be Black - Black - Black, but that is actually ONE
OHM. (I always have a hard time comprehending that one).

So I cant imagine how to color code ZERO Ohms...

One black band around the middle is a common marking.

Please note that there are SMD versions of these as well. They will be marked with a single zero(0).

You will often see these used to jump a trace in SMD applications.

So these things really *DO* exist???
I thought it was either a typo, or the webpage was made up by someone
who was clueless about electronics.

That seerms pretty goofy, but I do imagine some machines cant handle the
bare wires.....

I'm guessing they are just a piece of solid wire with a "shell" around
it.

They ca over pass a track without needing 2 vias.

Perhaps someone is sneaking "high temperature" (meaning ambient)
superconductors onto the market with no fanfare?

One ohm is brown, black, gold.

Zero ohm should be black, black, any.

Are you saying that approximately zero is good enough?

I have seen thee or four zeros, depending on the tolerance. They
were 5% and 1%. We used them on circuit boards when a pad wasn't needed.


I see that they now sell 0.05% as well:

I'm not sure I understand your question, but the third band is the
multiplier, and since the two first bands are zero, you can multiply
with anything you like. So, black, black, white would still be zero.

Now that I think about it, one ohm could also be black, brown, black.

Yes, see the point; I went off half-cock (approx) thinking the "any" was
tolerance. I suppose a minus power of ten multiplier would be good, too
(I forget the colours)...

Are you shitting me.....
How can there be a tolerance for ZERO Ohms?
Zero IS Zero....

That's just plain silly.... <LOL

Speaking of silly, next time you see someone wiring a light fixture or
lamp, ask them what the tolerance is for the wire they are using.... :)

Here we go with those initials "SMD" again. I keep seeing that in posts
on here and elsewhere. So I better ask...
What the heck does SMD mean?

Sorry about not including the definition:

I believe you are reading that chart wrong.

I have some resistors and checked them out. One is a brown black gold
and is 1 ohm. Another is brown black silver and is .1 ohms. That is
measured with a Fluke 87 VOM.

I don't know for sure, but maybe the resistors do not start off with a
black band. Don't have any loose resistors to check, but many on
circuit boards are a solid color with a black band in the middle.

SMD is surface mounted device. For resistors and capacitors they are
usually small and flat. They are usually silver colored on the ends.
That is there you solder them to the circuit board. The ICs will often
have what seems like very short leads. They lay flat on the circuit
board also.

Check out this youtube video as to what they are and ways to work with
them. For very much work it helps to have a good 10 to 20 power
stereo microscope.
