Zero-ohm link

From Wikipedia, the free encyclopedia

A zero-ohm link or zero-ohm resistor is a wire link used to connect traces on a printed circuit board that is packaged in the same format as a resistor. This format allows it to be placed on the circuit board using same automated equipment used to place other resistors instead of requiring a separate machine to install a jumper or other wire. Zero-ohm resistors may be packaged like cylindrical resistors, or like surface-mount resistors.

"000" and "0000" sometimes appear as values on surface-mount zero-ohm links, since these have (approximately) zero resistance. Alternatively, a single black line may be used to denote zero ohms using the resistor color code on a cylindrical zero-ohm resistor.
