EMI Suppression for FFCs
Thermoplastic EMI Shielding Films for FFCs
WILMINA®
SF-FC700 / SF-FC500
Overview
As OLED and QD-OLED televisions and 4K/8K displays continue to advance, effective electromagnetic interference (EMI) suppression for the flexible flat cables (FFCs) used inside these devices is becoming increasingly important.
TATSUTA’s WILMINA® SF-FC700 is a thin, lightweight thermoplastic EMI shielding film that offers excellent flexibility. It is well suited for noise suppression in FFCs used in televisions and other consumer electronic devices.
In automotive applications, FFCs are increasingly being considered as alternatives to conventional wire harnesses, creating demand for more reliable shielding solutions. To meet these requirements, TATSUTA developed SF-FC500, which offers heat resistance up to 125 °C and higher shielding performance than SF-FC700 through the use of a 10 µm aluminum foil shielding layer.
