Help 0 Ohm Resistor?

[Vikki]

Just putting together the JLM 99 pre's and one of the resistors is listed as 0 ohms, white body black band. Can't seem to find anyone in the uk who stocks them and get silly looks when asking for them, will a shorting link do the same thing? Is its purpose to stop rf and oscillation?

Just a link in a fancy package, wire works fine.

If it's not a fusable resistor, and i can't think why there should be one in this application, then just use a jumper.

 

[Vikki]

ok thanks.

They're also known as "zerohms."

Why bother making a zero-ohm resistor? It's easier for automated PCB-stuffing equipment to handle than a wire link would be.

> 0 ohms, white body black band

Mechanical mass-production stuffing-robots don't handle naked wire well. They do handle resistors well. So somebody invented the zero-resistance resistor. Where you need a jumper, you lay-out for a resistor, and specify zero ohms. The stuffing-robot grabs a resistor-shaped part from the 0-ohm bin and stuffs it.

If you can't find where you lost your $250,000 stuffing-robot, or you are not making a million of them, find some nimble-finger low-paid human (you) to bend, orient, stuff, and solder a jumper.

Puzzled me that one, thanks for the explanation. I think my first thought was an encapsulated one turn on a ferrie bead or something.

They can be usefull for humans too, where you do not want easy to use buss wire jumpers to lay flat on another trace that might have the wrong flavor voltage on it.

Circuitmaker won't allow entering 0 ohms as a value, so when using it as a drafting program I have to defeat the value display option and put something adjacent using the annotation option.

Yep Vikki a wire link is fine, the only reason we use them is theyre nice and easy to bend drop into resistor spaced holes. Also they look kinda cool, dontcha think? Very Channel...

Vikki;
We use them a lot at work thought they are the surface mount type.
We stuff or not stuff to add functions to pc boards.
They enable or disable options in the products.

Audiophile quality, 0ohm resistor. :grin:

And make sure to get the polarity correct, especially after the cryogenic treatment and electron coherence instillation.

I can't tell you how much it improved my sound. :razz:

But only in combination with the 500$ wood knob. :grin:

Vikki,
I see they are treating you like a female in a man's world...don't you worry I'm here for you. Do your thing.

Naah.
Vikki is an old forum member, she was with us even at the old place and we are proud and love our female members. She knows our jokes. We are not making fun of her.
We usually make fun of audiofools and their voodoo. :grin:

now if someone could just make a minus 10 ohm resistor, we wouldn't have to use transformers.

I actually had a manufacturer in China ask me to help them locate a negative resistor.

They were having a problem with a clock oscillator on a uC, and in reading the specs for the gate oscillator saw the language about "negative resistance" being involved in getting the external crystal to go. They searched catalogs to no avail.

The real problem with the oscillator was flux contamination and consequent high leakage current from a nearby pin with +5V on it to the gate input---it was biasing the CMOS inverter into a low-gain region. A cleaner process and a reduction in the external feedback resistor from 10M to 2.2M did the trick.

Ya just never know, do ya. Wow.
