EMIF04-EAR01F2
4-line IPAD™, EMI filter and ESD protection
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
Complies with the following standards
■ IEC 61000-4-2 Level 4, on output pins
– 15 kV (air discharge)
■ IEC 61000-4-2 Level 1, on input pins
– 2 kV (air discharge)
Applications
Where EMI filtering in ESD sensitive equipment is
required:
■ Earpiece and headset for mobile phones
■ PDAs
■ MP3 players
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.
