Zer-Ohm resistors?

What are zero-Ohm resistors used for? I have an AD converter unit where the source input signal is selected by means of ordinary jumpers. I have decided that I don't need the removable jumpers anymore and would like to solder a short piece of wire permanently for a more robust signal flow. Would a zero-Ohm resistor be better than a piece of good quality copper wire for this purpose?

BTW, how much resistance is actually there in a "zero-Ohm" resistor. I can't believe it's really zero. Must be a very small value, but not zero!

Thanks! 🙂

It's just a piece of wire.
I've been told by a plant manager that they are shaped like resistors so they don't have to have another set of tooling for the automatic board stuffing machines.

Obviously nothing has 'zero' resistance, however earlier on today when I purchased some of these, I did find it rather amusing that they specify a tolerance.

1%, one percent of what exactly? Zero? Surely they must be joking😉

And yes, I am using them simply as a wire link.

LOL! 😀 All that fuzz for just a piece of wire!

That's funny. 1% of zero is zero. 5% of zero is zero. Heck, any % of zero is zero! That spec is meaningless. 😀

Thanks a lot guys! Now I know what zero-Ohm resistors are. 🙂

Zero ohm resistor is a jumper or a piece of wire.
