Common Mode Noise Filter with ESD Protection
LCFEA Series
LCFEA Series
Description
This specification covers the engineering requirements for both Common Mode
Noise Filter (CMF) and ESD Protection especially for high speed differential
serial interfaces, such as USB 3.1 , USB 2.0 , MIPI D-PHY or HDMI, and RGB line,
LVDS line.
AEC-Q200 qualified common mode noise filter will help to choke and attenuate
the noise for the growing number of electronic applications in modern vehicles.
Features
• AEC-Q200 qualified
• Effective for suppressing common
mode noise and almost no effect for
high speed differential data line
• Differential mode cut-off frequency
up to 4.5GHz at -3dB
• Common mode filters and ESD
suppression devices integrated
• Low profile package
