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.

Features

High shielding effect

Product Shielding effect
1GHZ 10GHZ
SF-PC3900R1-C Above 80dB Above 85dB
SF-PC3900R2-C Above 85dB Above 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).
