| www..com (R) EMIF04-1502QCF 4 LINES LOW CAPACITANCE EMI FILTER AND ESD PROTECTION IPADTM MAIN PRODUCT CHARACTERISTICS: Where EMI filtering in ESD sensitive equipment is required : 8 7 6 5 LCD and camera for Mobile phones Computers and printers Communication systems MCU Boards 1 2 3 4 GND DESCRIPTION The EMIF04-1502QCF is a 4 line highly integrated device designed to suppress EMI/RFI noise in all systems subjected to electromagnetic interferences. This filter includes an ESD protection circuitry, which prevents the device from destruction when subjected to ESD surges up 15kV on the input pins. BENEFITS QFN 2x2mm 8 pins (Dot on package indicates pin 1) Table 1: Order Code Part Number EMIF04-1502QCF Marking F4 Figure 1: Pin Configuration (back side) Low-pass Filter Input Output EMI symmetrical (I/O) low-pass filter High efficiency in EMI filtering Very low PCB space consuming: 2mm x 2mm Very thin package: 1 mm max. 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 1 Low-pass Filter Input Output 8 2 Low-pass Filter Input Output 7 3 Low-pass Filter Input Output 6 COMPLIES WITH THE FOLLOWING STANDARDS: IEC61000-4-2: Level 4 input pins 15kV (air discharge) 8kV (contact discharge) 4 Figure 2: Basic Cell Configuration 5 MIL STD 833E - Method 3015-6 Class 3 Input 1 C1 C2 Output 2 Typical line capacitance = 13pF @ 3V R = 160 TM: IPAD is a trademark of STMicroelectronics.
