Description
The EMIF02-SPK01 is a highly integrated device
designed to suppress EMI/RFI noise in all
systems subjected to electromagnetic
interferences. The EMIF02 Flip-Chip packaging
means the package size is equal to the die size.
This filter includes an ESD protection circuitry
which prevents damage to the application when
subjected to ESD surges up 15 kV.
