Littelfuse LCFE Common-Mode Noise Filters

Littelfuse LCFE Common-Mode Noise Filters meet engineering requirements for common-mode noise filters and ESD protection, especially in high-speed differential serial interfaces such as USB 3.1, USB 3.0, MIPI D-PHY, or HDMI. Littelfuse LCFE is effective at suppressing common-mode noise and has almost no effect on high-speed differential data lines. These filters feature differential-mode cut-off frequency up to 10.5GHz at -3dB.
