Zero ohm resistor ?

yesterday I brough a x'mas three kit set for soldering, But the circuit use four nos. of zero ohm resistor.Can any person know what is that mean, can we use jumper wire to substitute ? Thank you.

2 possibilities...

- it's just a jumper wire to ease crossing on the pcb

- it's used as "fusible resistor" for protection of the circuit

use

sounds like a jumper to accommadate single sided pbc layout

TOP POST REPAIRED! Ecch!

Yes. However "Zero Ohm Resistors" are commonly used to select options or in some cases (since the actual resistance is about.01 ohms) as a current sense resistor.

Never used as a "fusible resistor" since it will carry much more current than any other element in the circuit! Also, not made to open readily! A diode is a better fusible component.

Zero Ohms resistors are used for wire bridges on single sided printed circuit boards. They are used instead of pieces of wire as they can be handled easier, especially by placing machines. Ever saw a board with tens of them. Obviously designed by a lazy or incompetent pcb designer. As these resistors are made to replace jumper wires, you can replace them by the jumper wires they replace :)

Sorry, not quite. The old "crystal" diodes would fail open pretty reliably, but modern diodes frequently fail shorted, too.

Fusible resistors have their place. The spec tells their current rating. Also, several manufacturers make small axial lead fuses which have the same form factor as a 1/4W resistor.

Good luck Chris

Then YOU should use the fuse!
