Product Overview

The EMI2121 and SZEMI2121 are integrated common mode filters with ESD protection, designed for high-speed serial digital interfaces such as USB2.0. These devices offer both EMI filtering for differential data line pairs and ESD protection for data pairs and supply inputs. They provide significant cost and space savings over discrete solutions due to their highly integrated design. With a large differential mode bandwidth exceeding 2 GHz and high common mode stop band attenuation, they are ideal for mobile phones, digital still cameras, and automotive interfaces requiring robust EMI reduction and ESD protection.
