EMIF10-LCD01C2 |
|
10 LINE EMI FILTER |
IPAD™ |
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-LCD01C2 is a 10 line 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.
BENEFITS
■EMI symmetrical (I/O) low-pass filter
■High efficiency in EMI filtering
■Very low PCB space consuming: < 7mm2
■Coating resin on back side
■Very thin package: 0.69 mm
■High efficiency in ESD suppression on input pins (IEC61000-4-2 level 4)
■High reliability offered by monolithic integration
■High reducing of parasitic elements through integration and wafer level packaging.
■Lead free package
COMPLIES WITH THE FOLLOWING STANDARDS:
IEC61000-4-2:
Level 4 input pins 15kV (air discharge) 8kV (contact discharge)
Level 1 output pins 2kV (air discharge) 2kV (contact discharge)
MIL STD 833E - Method 3015-6 Class 3
Lead free coated Flip-Chip (25 bumps)
