Description

The EMI2121 is an integrated common mode filter providing both ESD protection and EMI filtering for high speed serial digital interfaces such as USB2.0.The EMI2121 provides EMI filtering for one differential data line pair and ESD protection for one data pair plus a supply input such as USB2.0 Vbus or USB ID pin. It is supplied in a small RoHS compliant WDFN8 package.
