Zero-Ohm Resistors: Uses and Benefits | Enrgtech Blog

 Zero-ohm resistors

A Zero-ohm resistor is simply a resistor with zero ohms. It’s a through-hole resistor that has been manufactured to have zero ohm of resistance and is marked with a single black band.  A surface-mount ceramic resistor has single or multiple numbers of zeros to represent the zero-ohm resistance. It is pretty much like a jumper wire that is shaped like a resistor. Why do you need a zero-ohm resistor? Why not just use a jumper?




Uses of a Zero-ohm resistor.

An alternative for jumper wire

The use of jumpers in circuits is common. They allow for unmatched flexibility. However, they are only applicable if you are going to solder manually. That is not the case in mass production. Mass production involves pick-and-place machines which do not have the ability to handle jumper wires. An extra machine would be required for that making the cost of production to rise. To avoid that, a zero-ohm resistor is used. It saves both cost and assembly time.
