10 LINES EMI FILTER
AND ESD PROTECTION
MAIN PRODUCT CHARACTERISTICS:
Where EMI filtering in ESD sensitive equipment is
required :
LCD for Mobile phones
Computers and printers
Communication systems
MCU Boards
DESCRIPTION
The EMIF10-LCD01F1 is a 10 lines highly
integrated devices designed to suppress EMI/RFI
noise in all systems subjected to electromagnetic
interferences. The EMIF10 flip chip packaging
means the package size is equal to the die size.
This filter includes an ESD protection circuitry,
which prevents the device from destruction when
subjected to ESD surges up 15kV.
