– 15 kV (air discharge)
– 8 kV (contact discharge)
Application
Where EMI filtering in ESD sensitive equipment is
required:
■ MultiMediaCard for mobile phones, personal
digital assistant, digital camera, MP3 players...
Description
The EMIF04-MMC02 is a highly integrated device
designed to suppress EMI/RFI noise for a
MultiMediaCard port. 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 it is
subjected to ESD surges up to 15 kV.
