MULTIMEDIACARD™
■
DESCRIPTION
TheEMIF04-MMC02F1 isa highly integratedarray
designed to suppress EMI / RFI noise for
MULTIMEDIACARD™ port filtering.
TheEMIF04-MMC02F1 flip-chippackaging means
the package size is equal to the die size. That's
why EMIF04-MMC02F1 is a very small device.
Additionally, this filter includes an ESD protection
circuitry which prevents the protected device from
destruction when subjected to ESD surges up to
15 kV.
