Product Overview

These are thinner types of shielding film with a high shielding effect. With the miniaturization of electronic devices and the increase in mounted components, the trend of downsizing is continuing. In addition, the demand for high shielding in the high frequency range has been increasing in recent years, and our products can meet this demand. Depending on the required shielding effect and thickness, you can select from SF-PC®3900R1-C or SF-PC®3900R2-C.


  • High shielding effect

    ProductShielding effect
    SF-PC3900R1-CAbove 80dBAbove 85dB
    SF-PC3900R2-CAbove 85dBAbove 95dB
  • Realize the total thickness of 12µm/13µm

    While maintaining a high shielding effect, the total thickness is as thin as 12μm (SF-PC3900R1-C) and 13μm (SF-PC3900R2-C).
