EMI shielding film
WILMINA®
Shielding film for high-speed signal transmission FPC (capable of small-diameter GND)
WILMINA®
SF-PC®4300-C
UL94 VTM-0 to be certified

Product Overview
Where a shielding film is used, the SF-PC4300-C can maintain a stable resistance value and secure high shield performance even with GND to the shielding film is small in diameter (φ0.5). By using an isotropic conductive adhesive and increasing the number of contacts of conductive fillers in the GND opening, a stable joint resistance value is achieved even with a small diameter GND opening.
Features
-
High shield performance
Offers top-class performance among all TATSUTA products.
SF-PC4300-C: Over 80dB/1GHz, over 90dB/10GHz -
Stable joint resistance value
Stabilization of the joint resistance value is realized by increasing the number of contacts of conductive fillers in the GND opening with the adoption of an isotropic conductive adhesive.
SF-PC4300-C: GND diameter φ0.5mm 50mΩ
