Flat Flexible Cable

Click here for a PDF datasheet

The drive towards higher performance yet smaller sized cables has led Fujikura to develop its own range of flat flexible cables (FFCs). Used in conjunction with the myriad of connectors now available, FFCs are more reliable and cost effective then standard wiring systems.

Features

extremely compact designs for cost efficiency
unbeatable flexibility for the most constrained of applications
harness configurations possible using Fujikura's branching system
constructions incorporating EMI/RFI counter measures
pre-assemble to PCB or other wiring materials
reliable performance over extended periods
operational durability exceeding 1 million bending cycles

Applications

PCB jumper
printers
CD players
FDD
LCD displays

Bending Property

Shielded FFC

Due to the high wiring density currently in use, the effects of electromagnetic interference becomes more and more prevalent within today's electronic designs. To combat this, Fujikura are able to offer a shielded FFC using 9um copper mylar film as the shield with a connection made to the ground wire by ultrasonic welding.
