TM
EMI FILTER INCLUDING ESD PROTECTION
APPLICATIONS:
Where EMI filtering in ESD sensitive equipment is
required :
Computers and printer
■
Communication systems
■
Mobile phones
■
DESCRIPTION
The EMIF08-2005QEJ is a highly integrated device
designed to suppress EMI/RFI noise in all systems
subjected to electromagnetic interferences. Additionally,
the EMIF08-2005QEJ filter includes an ESD protection
circuitry which prevents destruction when subjected to
ESD discharge up to 15kV.
BENEFITS
EMI symmetrical low-pass filter
■
Low PCB space consuming: 9 mm
■
■ Very thin package < 1 mm
■ High reliability offered by monolithic integration
