hey guys
is there any point to a zero ohm resistor
:-\  :-\  :-\  :-\

thanx spleblem

A zero ohm resistor is a jumper wire for a pcb that can be installed by the same machine that installs resistors.

:)a super conductor isent that suposed to be zero ohms , and i supose if ya take a resister out ya have no ohms at all so hence the zero ohms hmm ill leave that to audio guru, him exspert  in the electronics feild

Zero ohm? All wire has some resistance. You can look at a zero ohm resistor as a value with not enough resolution. Add the decimals places and you would have some small value there.

What I know is, some products keep a resistor footprint for adding EMC components for Lab test while they will use a 0ohm resistor for shipment product...... what for...... reduce cost  :p

We use 0 ohm SMD resistors all the time. They are mainly used as links. We design the boards so there are different configurations available. The resistors are placed to select different options.

Hello
OK you got me where can you buy zero  Ohm resistors, I think a jumper wire has more Ohms then zero.

Hi,
  I've seen jumpers inside TVs before soldered right along with resistors. R they those staple looking things?
???
What are they used for?
What are they?

It acts like a small inductor in some cases.
I missed this post before. Not quite sure hore you can make this statement. A small chip of metal film with 0 ohms would have such an insignificant inductance it would be useless. About the only way I could see this happening is if it was a wire wound 0 ohm resistor

Actually, wire wound resistors do have inductance. As far a wire, it's about 20nH/inch.

Yup... zero ohm jumpers can be/are used for configuring different options. They are also used a as "bridge". When you have to keep cost's down, manufacturers use them to avoid having to go to a double sided PCB. A few "jumpers" are a LOT cheaper than drilled plated via's on a multi-layer PCB (as in double sided and up).
