EMIF02-USB01 ® IPADTM 2 LINES EMI FILTER INCLUDING ESD PROTECTION MAIN APPLICATION ESD protection and EMI filtering for USB port. ■ DESCRIPTION The EMIF02-USB01 is a highly integrated array designed to suppress EMI / RFI noise for USB port filtering. The EMIF02-USB01 flip-chip packaging means the package size is equal to the die size. That's why EMIF02-USB01 is a very small device. Additionally, this filter includes an ESD protection circuitry which prevents the protected device from destruction when subjected to ESD surges up to 15 kV. BENEFITS 2 lines low-pass-filter + 2 lines ESD protection High efficiency in EMI filtering Very low PCB space consuming: 2.5 mm2 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 & wafer level packaging. Flip Chip package PIN CONFIGURATION 3 2 1 ■ ■ ■ A ■ ■ B ■ ■ C D COMPLIES WITH THE FOLLOWING STANDARDS : IEC61000-4-2 level 4 15kV (air discharge) 8 kV (contact discharge) on input & output pins.
