Introductions

The traditional ESD protection or EMI filter function is resolved by a single individual component as solution. However, the improvement quality of mobile phone and high EMI sensitivity of IC makes the designer need to improve anti-interference capability of phone, as a result, some of the technical limitations has been revealed. Therefore, each manufacturer of protection component actively develops solution for the next generation of chip ESD protection / EMI filters. SFI launched the dual function EMI + ESD products in order for market demand, currently, the main market applications is for mobile phones, PDAs, DSCs (digital camera) as well as MP3 and other portable products.
