Finally, good riddance.

Just kidding.

500 x zero-ohm resistors for $4.



I love this concept! A resistor with no resistance! It's like buying a box of chocolates with no chocolates in it, or a wine bottle with no wine in it.

I'm not sure what their tolerance is, but I suppose 5% of zero is still zero, so that's not a huge issue.

This begs the question Nick, what on earth would you use those for?  Build a sculpture?

[Reply #379 on:]

I thought someone would ask that.

They must be useful, right, or they wouldn't make them?

One use is to make something look fancier than it really is. :O

They are also described as "link" so I suppose in practice you might put them onto a circuit board as a wire link so that an automatic device could install them the same way as a resistor. Might be easier for the mechanics to handle than plain wire.

Correct.

You do of course realize that it is not truly a 0 ohm resistor, such a component doesn't exist at room temperature.

But then why do they make ... Oh, I won't go there

I think that's it, these were maybe more popular back in the day when single-sided PC boards were more common, and needed jumpers.

And here I was thinking you can get a room temperature superconductor for short cash.  Ah well, back to mining zero point energy and building my Phlogiston flywheel..

they still make and use them in their SMD form for the same reasons, if you need to have some configurable option at the time of manufacture but dont want to make different boards add pads and use a "0 ohm resistor" to jump them since pick n place machines can grab them

So essentially, it's a piece of wire with some plastic molded over it and a single stripe painted over it.  Ah the good ol' days.

Rats! I haven't bought a superconductor? I thought they were a bit cheap ...

Either that, or your meter is a fluke.   (sorry, I had to say it.)

Nice meter, I have a couple of older mode 87s.  A hint, when measuring low value resistances, first short your meter leads together, turn to the resistance mode and then press the 'REL' button. That will then factor out ('zero out') your meter lead resistance and the display will say 'rel' to remind you that the reading is the resistance value above the meter leads resistance.
