Flat Flex, Ribbon Jumper Cables

Flat flex jumper cables are one of the most versatile and reliable types of cable used within the electronics industry. Connecting electrical components in applications such as audio or video systems, these cables are designed with a thicker insulation layer and a thicker conductor than standard jumpers. As the name implies, flat flex jump cables are composed of a flat ribbon cable, two crimp connectors on each end, and a snap-on terminal that makes contact through a pin. While flat flex jumper cables are most commonly used in audio and video systems, they are also found in several other applications, such as the transport of data and power.

Flat flex jumper cables are typically used for low voltage applications, due to their thin insulation and thinner conductor compared to standard jumper cables. The flat flex cables are most commonly stranded copper, though other metals such as aluminum are sometimes used. The low-voltage application of these cables means that they are suitable for connecting circuit boards, but require special consideration when used in higher voltage applications, such as DC and AC power.

Flat flex jumper cables come in a variety of sizes and configurations. The most common type is a two-conductor ribbon with 26 AWG gauges, the same size as most computer terminals. These cables have a flat cross-sectional profile which helps keep the cable strands close together and improves electrical conductivity. Other sizes of flat flex cables also exist, such as 42 AWG and 56 AWG, which are suitable for low-voltage applications such as speaker wire, microphone cables, and Ethernet connections. Some flat flex cables also have larger conductors, such as 14 AWG, which can be used in higher-voltage applications.

The working principle of a flat flex jumper cable is relatively simple. Each conductor is crimped onto a matching terminal on either side of the cable, and then connected to the component parts. The conduction is accomplished through the contact between the two terminals, and is further aided by a coat of dielectric material around the conductor. This dielectric material helps to reduce the potential for electrostatic discharge and higher impedance. The presence of the dielectric also helps prevent the buildup of charges in the wire, which can result in arcing or corrosion.

Flat flex jumper cables are a popular option for the interconnection of electronic components due to their low-cost and flexible design. In addition, their simple construction makes them easy to install in a variety of applications. Flat flex cables are often used to connect PCBs as well as cables in audio/video systems, power lines, communications systems, and other areas. Their ability to withstand mechanical stress, flexibility, and low-voltage operation make them an ideal choice for many applications.
