AUTOMATED PCB JUMPER

0 Ohm Resistor Color Code (Zero-Ohm Jumper)

Q: Why do 0 ohm resistors exist if they have zero resistance?

Modern circuit boards are assembled by high-speed automated pick-and-place robots. These machines handle standardized tape-and-reel resistor packages effortlessly. Using a 0 ohm resistor allows manufacturers to jump traces or select circuit options without purchasing separate wire-bonding or hand-soldering equipment.

Q: What color is a 0 ohm resistor?

A standard through-hole 0 ohm resistor has a single Black band printed around the center of its ceramic body. Some military or 3-band packages indicate it with Black-Black-Black.

Q: What is the tolerance of a 0 ohm resistor?

A 0 ohm resistor does not have a percentage tolerance because zero cannot be expressed as a percentage. Instead, component datasheets specify a maximum residual resistance (typically < 0.05 Ω or 50 mΩ) and a maximum continuous current rating (such as 1A or 2A).

Q: What is the SMD code for a 0 ohm resistor?

Surface-mount zero-ohm resistors are stamped with "0", "000", "0000", or "0R0" on their top protective lacquer.

A 0 ohm (zero-ohm) resistor is essentially a precision wire link packaged in a standard axial through-hole or SMD chip footprint. It is widely used in automated PCB assembly to bridge traces, configure board options, or act as an easily removable jumper without redesigning circuit boards. In the color band system, it is marked by a single Black stripe at the center.
