EMIF04-10006F2
IPAD™
4 LINES EMI FILTER
AND ESD PROTECTION
MAIN PRODUCT CHARACTERISTICS
Where EMI filtering in ESD sensitive equipment is
required:
■
Mobile phones and communication systems
■
Computers, printers and MCU Boards
DESCRIPTION
The EMIF04-10006F2 is a highly integrated
devices designed to suppress EMI/RFI noise in all
systems
subjected
to
electromagnetic
interferences. The EMIF04 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. This device
includes four EMIF filters and 4 separated ESD
diodes.
BENEFITS
■
EMI symmetrical (I/O) low-pass filter
■
High efficiency in EMI filtering
■
Lead free package
■
Very low PCB space consuming:
2.92mm x 1.29mm
■
Very thin package: 0.65 mm
■
High efficiency in ESD suppression
(IEC61000-4-2 level 4)
■
High reliability offered by monolithic integration
■
High reducing of parasitic elements through
integration and wafer level packaging.
COMPLIES WITH THE FOLLOWING STANDARDS:
IEC 61000-4-2 level 4:
15kV (air discharge)
8kV (contact discharge)
MIL STD 883E - Method 3015-6 Class 3: 30kV
