Topic: Drawback of using Resistors wires as Jumpers!!! (Read 972 times) previous topic - next topic

Dear Friends,
I have a question. Normally we used 1/4 watt resistors. We solder the resistors on the circuit and trim-off the excessive length of wire. Normally i make single-sided PCB and i have to install jumper wires.My question is can we use these trimmed resistors wires as a bridge/jumper in a circuit? Is it a good practice?

Yes of course it is.  These wires are tinned copper and therefore ideal for use as jumpers

That's just fine, don't even cut them off, just bend to the place they have to be if they'll reach.

I've used them as well, I'm sure it's OK, but curiously I've noticed that a lot of component leads are magnetic, so not sure what they're made of exactly, but some are more than just tinned copper.

They are probably nickel plated steel and not really recommended for jumpers.

Why not? If the wire is good enough for the lead up to a component it is good enough for a link. I have been doing this for over 40 years and have not come across any problems at all.

How's that for bulletproof logic.  ;)

PS: I just tested a 47k ohm resistor that was laying on my desk. No magnetic attraction at all. Suspect it's just tin plated copper wire.

Most of my resistor/capacitor/diode wires are magnetic, though not all.

They make wonderful jumpers regardless.
Obviously using the wire off a 1/8w resistor for the main power feed to something that wants multiple amps won't work out well, but that's fairly obvious I think.

Using steel would only be an issue with high currents - its resistance is higher than copper, but of course all metals are good conductors compared to a resistor.  Steel is used because it is cheaper than copper.
