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

• Ceramic multilayer type SMD

component

• Non-polarized product

• Conforming to RoHS directive.

• ±15kV air, ±8kV contact ESD

protection (IEC 61000-4-2 Level 4)

• High temperature soldering

guaranteed: 260°C/10 seconds
