MIL-PRF-32159 Zero-Ohm Resistor

A mil spec surface mount resistor with a value of zero ohms, note the different sizes below. Zero-Ohm Resistors are used as interconnect points on a PWB. They may also be used to tie two circuit points together while in system test so an internal trace may be accessed but removed in the final application, removing the physical test point.

These resistors do have a small non-zero resistance, so they do dissipate heat. The resistance ranges between 0.030, 0.060 and 0.150 ohms depending on the termination.
