and ESD protection).
Description
The EMIF02-MIC01F2 is a highly integrated
device designed to suppress EMI / RFI noise for
microphone line filtering.
The EMIF02-MIC01F2 Flip Chip packaging
means the package size is equal to the die size.
This is why the EMIF02-MIC01F2 is a very small
device.
Additionally, the filter includes an ESD protection
circuit to prevent damage to the protected device
when subjected to ESD surges up to 15 kV.
