what are the uses of zero ohm jumper resistors?

[jarthel]

I was looking at the mouser catalog and I found this resistor. they are not exactly 0ohm but the catalog says it's 0.01ohm max.

what are the uses for them? why not just a piece of wire?

thanks for the replies.

They were used as trace jumpers for single side boards.
With single side boards it's not always possible to avoid crossing traces.
Looks much better, easier for production.

Japanese amp boards often had long jumper wires.
The fancier ones had/have copper overhead strips for powersupply rails.

trace jumpers? like if a pcb is suppose to have a resistor but the design was changed and the resistor was removed. you place a zero ohm resistor in its place?

I bought some just for the sake of having some.

that's the same reaction that everyone I showed it to.......

from what I know, it was made for automated machines where the machine was designed to handle resistors but not plain wires........not sure though. just a guess.........

it's only 6 cents in mouser so it's not much but leads cut from resistors are just as good

it does look and sound cool though

you can also use it to trick people saying that your PCB layout is so well designed that you never needed a jumper.

I actually got my 100pc pack for an equivalent of US$0.40 with the size of 1/8w resistors.

Deceive the audience by adding a couple of color stripes
(great thing about digital cameras is that you can read every component and the schematic from a picture, this one is Mr Greg Ball's first OPA627 entry GB-amp lookalike from Germany )
Spot the jumpers :

in raon? what shop? I'll asking my dad to buy me a desoldering iron next week so I might as well ask him to buy other stuff for me.

thank you.

No. You had two traces that needed to cross on a single sided pcb, you would bridge one over the other with a zero ohm jumper.
Of course yopu can also use them for engineering changes, but that's another purpose.

yep. in deeco 2nd floor. look in the resistors section.
