EMIF04-MMC02F3
4 LINES EMI FILTER AND ESD PROTECTION FOR MULTIMEDIA CARD
Main product characteristics:
Where EMI filtering in ESD sensitive equipment is required :

MultiMedia Card for mobile phones, Personal Digital Assistant, Digital Camera, MP3 players... Flip-Chip (11 bumps)

Description
The EMIF04-MMC02F3 is a highly integrated device designed to suppress EMI/RFI noise for MultiMedia Card ports. 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 to 15kV.
