Flat Flexible Cables (FFC) and Ribbon Jumper Cables (RJ) have become ubiquitous in the modern world and are perhaps most widely used in the consumer electronics industry. FFC and RJ cables are used to interconnect printed circuit boards (PCBs) and electronic components in applications like mobile phones, computers, and consumer electronics. Despite the simple concept, FFC and RJ cables are incredibly versatile, able to be adapted and customized for a wide variety of applications. In particular, FJH-20-D-31.75-4, a flat flexible cable and ribbon jumper cable from FJH, is a popular choice for connecting a range of components in a variety of electronic applications. In this article, we will discuss the application fields and working principle of FJH-20-D-31.75-4.

Flat flexible cables (FFCs) and ribbon jumper cables (RJs) are flexible cables with multiple conducting wires arranged in side-by-side parallel flat planar shapes. FJH-20-D-31.75-4 is a flat flexible cable and ribbon jumper cable composed of 20 individual conductors with 0.3mm pitch, 31.75mm square, and 4.8mm thick. The connector at both ends facilitates secure and efficient connection between components, making it ideal for those looking for a simple yet secure connection.

Application fields

FJH-20-D-31.75-4 is suitable for a variety of applications, in particular it excels in printer and copier applications. The 0.3mm pitch is ideal for connecting high-speed serial data paths between high-performance chips or systems. In printer and copier applications, this insures quick and stable transfer of large image files. Additionally, the wide range of temperatures at which this cable is able to work, -40°C to +105°C, allows it to be used in some of the harshest environments.

The highly flexiblity of the FJH-20-D-31.75-4 also makes it ideal for use in automotive applications. The ability to be used in temperature ranges as extreme as -40°C to +105°C ensures reliable operation in even the most extreme driving conditions. In addition, the flat nature of the cable allows for a more compact setup than round cables and is able to withstand multiple flex cycles, making it an ideal choice for wiring in tight spaces.

Working principle

FJH-20-D-31.75-4 achieves its wide range of applications due its high-performance construction. The cable is composed of tin coated copper conductors, providing excellent electrical conductivity and low impedance, as well as insulation that is highly resistant to temperature, moisture, humidity, and abrasion. The insulation consists of alternating layers of PVC and glue, providing superior flexibility and durability.

The flat flexible cable and ribbon jumper cable is constructed with an individual conductor for each connection. The pitch and size of the conductors fit perfectly together, eliminating any gaps, thus providing a secure connection. Additionally, the connectors on each end provide an easy and secure way to connect the conductors to components. The connectors are securely attached to the cable, allowing for multiple flex cycles without breaking.

In conclusion, FJH-20-D-31.75-4 is a versatile flat flexible cable and ribbon jumper cable from FJH which is well suited for a wide range of applications, particularly in the printer, copier, and automotive fields. Its high-performance construction allows for secure and efficient connections, and its flexiblity allows for use in a range of temperatures from -40°C to +105°C. Thanks to its sturdy construction and ease of use, FJH-20-D-31.75-4 is a popular choice for those seeking reliable and efficient connections.
