Description
The EMIF04-EAR01F2 is a 4-line highly integrated device designed to suppress EMI/RFI noise in all systems subjected to electromagnetic interference. The EMIF04 Flip Chip packaging means the package size is equal to the die size.
This filter includes ESD protection circuitry, which prevents damage to the application when subjected to ESD surges up 15 kV.

Features
■ EMI (I/O) low-pass filter
■ High efficiency in EMI filtering
■ High density capacitor
■ Very low PCB space occupation: 1.92 x 1.42 mm²
■ Very thin package: 0.65 mm
■ High efficiency in ESD suppression on external pins (IEC 61000-4-2 level 4)
■ High reliability offered by monolithic integration
■ High reduction of parasitic elements through integration and wafer level packaging

Applications
Where EMI filtering in ESD sensitive equipment is required:
■ Earpiece and headset for mobile phones
■ PDAs
■ MP3 players
