EMIF01-10018W5
Application Specific Discretes
A.S.D.
MAIN APPLICATIONS
Where EMI filtering in ESD sensitive equipment is required :
Computers and printers
Communication systems
Mobile phones
MCU Boards
DESCRIPTION
The EMIF01-10018W5 is a highly integrated array
designed to suppress EMI / RFI noise in all systems
subjected to electromagnetic interfer ences.
Additionally, this filter includes an ESD protection circuitry
which prevents the protected device from de struction when
subjected to ESD surges up to 15 kV.
BENEFITS
Cost-effectiveness compared to discrete solution
EMI bi-directional low-pass filter
High efficiency in ESD suppression.
High flexibility in the design of hi gh density boards
Very low PCB space consuming : 4.2 mm2 typically
High reliability offered by monolithic integration
COMPLIES WITH THE FOLLOW ING STANDARD:
IEC 1000-4-2 15kV (air discharge)
level 4 8 kV (contact discharge)
MIL STD 883C - Methode 3015-6 Class 3
