EMIF04-EAR01F2
IPADTM 4 line EMI filter and ESD protection
Main applications
Where EMI filtering in ESD sensitive equipment is required:

Earpiece & Headset for Mobile phones PDAs MP3 players Flip-Chip (11 Bumps)

Description
The EMIF04-EAR01F2 is a 4 lines highly integrated devices designed to suppress EMI/RFI noise in all systems subjected to electromagnetic interferences. The EMIF04 flip chip packaging means the package size is equal to the die size. This filter includes an ESD protection circuitry, which prevents the device from destruction when subjected to ESD surges up 15 kV.
