APPLICATIONS:
The EMIF04-2005QCF is a highly integrated device
designed to suppress EMI/RFI noise in all systems
subjected to electromagnetic interferences. Additionally,
the EMIF04-2005QCF filter includes an ESD protection
circuitry which prevents destruction when subjected to
ESD discharge up to 15kV.
