Strange Resistor. Only has one band

Has anyone else seen a resistor like this before? I am having trouble working out the resistance.
It only has one band (black). Picture below.

Anyone have any idea what it is? I am a bit of a noob sorry if the answer is obvious. Google kept telling me the minimum number of bands was 3

Thanks for looking.

Hi @Tony254187

I believe this is a zero-ohm resistor. If you have a multimeter capable of measuring resistance, it may be wise to double check with that. Zero-ohm link - Wikipedia

Hi Tony,

I too was confused by @Ezra224017 is bang on here. I don’t think I’ve ever seen a 0 ohm resistor in action before so it is definitely a curveball for a beginner.

First time I’ve seen one as well. But I’ve very familiar with the concept. The last PCB I designed 25 y/o had holes and a Resistor number for them. It was a Stepper Motor controller which could possibly on a blue moon have a Resister in the winding circuit. The paint mask and the instructions clearly specified R0 Ohms otherwise, but one chap thought it meant 100 Ohms. Needless to say it didn’t step. This would make a good item for the “Dull Man” FB Group.

Thanks everyone! it is indeed a 0 Ohm resistor!!

That also explains why I have it left over after finishing my kit. The instructions called for a bridging wire and I just used a bit of a clipped resistor leg instead of this (didn’t realise they included it).

Thanks again! It seems strange that it would even exist in the first place when plain wire does the same thing. Unless it does do something more? Please correct me if I am wrong.

Kind Regards,

Tony

Hi Tony
It could be a “zero ohms” resistor or in short just a piece of wire.
These links are produced in this form to allow an automatic “pick and place” machine to insert a plain wire link into a board just like a conventional resistor. here machines have trouble with just a piece of wire.

Thanks for explaining why they exist! That makes sense. I guess it is easier for a mechanical arm/hand to hold than a plain wire

Hi Tony
That’s the reason
