Product Overview
With the launch of the new 5G communication standard, the rapid spread of electronic devices capable of radio frequency/high-speed signal transmission is expected to explode. In connection with this, measures that suppress noise from inside and outside are essential for FPC used in such electronic devices. The SF-PC3100-C and SF-PC3300-C offers top-class shield performance among all TATSUTA products, and can be used as noise suppression measures in high frequency ranges.
