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.
