Flat ribbon cable is a type of electrical cable designed to facilitate the organized and efficient transmission of signals and power.

Each conductor within the flat ribbon cable is typically insulated separately, and the conductors are usually color-coded to simplify installation and troubleshooting. The flat design not only makes it easier to handle and route the cable but also helps reduce electromagnetic interference (EMI) by keeping the conductors close together and maintaining consistent spacing. This arrangement can improve signal integrity and reduce noise in sensitive electronic systems.

Flat ribbon cables come in various configurations, including different numbers of conductors and pitch sizes (the distance between the centers of adjacent conductors). They are used in a wide range of applications, from computer internal connections and data transmission to consumer electronics and industrial machinery. In computer systems, for instance, they are often used for connecting internal components like hard drives, CD/DVD drives, and floppy drives to the motherboard.
