Flat flex jumper cables, commonly referred to as FJH-20-D-02.12-4, are an advanced type of ribbon jumper cables designed to meet the power and board connection requirements of modern electronic devices. FJH cables offer a low-profile connection that allows higher density connections to be made in a substantial reduction in space.

The flat flex technology used in FJH cables offers several advantages over traditional ribbon jumper cables. The key feature of this technology is the use of a flat flexible cable that allows for more connections per board than the traditional flat ribbon cable. This means that fewer components are required and a more customized connection can be created. Additionally, the flat flex design allows for a greater degree of flexibility, which makes it easier to route the cables around other components. Due to their flexibility, FJH cables can also fit into more complex circuit layouts, and allow for better heat dissipation.

FJH cables are primarily used for power and board connections in electronic devices, such as mobile phones, tablets, cameras, and medical equipment. They are also used in PDA (Personal Digital Assistants) and embedded application devices, as well as providing connection to printed circuit boards and testing equipment. Some of the latest applications for FJH cables include home entertainment appliances, security systems and power distribution systems.

The working principle of FJH cables is based on the connection of two flat flexible cables to form a single cable assembly. The contact between the two cables is then soldered or crimped, depending on the application. The connecting wires used in the FJH cables are usually ribbon cables with a minimum diameter of 24AWG and a maximum of 28AWG, allowing for transmission of power and signals at the same time. Additionally, the wires are insulated with an FEP, Polyimide or HDPE insulation that can protect against temperature, shock, and chemical vapours.

FJH cables are typically used in applications that require highly reliable connections, for example in military and aerospace applications. They are also popular in on-board applications which require high power density, as the cables are lightweight and flexible, allowing them to fit into tight spaces with fewer components required. Finally, they are used in telecommunications in optical fibre applications, providing extremely reliable connections for long distances.

In conclusion, FJH-20-D-02.12-4 flat flex jumper cables are a reliable and customized connection solution for a variety of power and board connection requirements. They provide a low-profile connection that allows for higher density connections in a reduced space, while also being easy to install and route. Additionally, the insulation used in the cables can protect against temperature, shock and chemical vapours, making them ideal for applications that require reliable and highly durable connections.
