Polyester ribbon 9900 series

9900 Transparent foil Transparent EMI / RFI shielding foil Transparent EMI / RFI shielding foil 9900 serie is an polyester film with a layer of transparent conductive coating. The foil provides excellent electric and eletromagnetic shielding 40-70 dB at 10 Khz untill 300 Mhz and 25-40 dB from 300 MHz untill 22 Ghz. In addition to EMI / RFI / EMC shielding it is also used for grounding and static discharge applications. Typical applications are transparent shielding panels for visual displays in instrumentation equipment, control panels and computers. The light transmission is 65-95%, depending on electrical conductivity (20-5 Ohm/sq). Duo to the transparency, Transparent EMI / RFI shielding foil 9900 serie is the optimal choice for optical clarity. For TEMPEST sides or radar / telecom protection large dimensions are available.
