EMIF01-5250SC5 ® EMI FILTER WITH ESD PROTECTION Application Specific Discretes A.S.D.TM MAIN APPLICATIONS Where EMI filtering in ESD sensitive equipment is required : Mobile phone : handsets and accessories RF communications DESCRIPTION The EMIF01-5250SC5 is a highly integrated T-filter designed to suppress EMI / RFI noise on I/O ports of mobile phones or RF communication equipment. This filter includes ESD protection circuitry which prevents device destruction when subjected to ESD discharges. The comprehensive layout of the EMIF01-5250SC5 filter allows design flexibility on high density boards. SOT23-5L (SC-59A) FUNCTIONAL DIAGRAM FEATURES T-filtering functions for 2 wires. ESD protection of 15 kV (air discharge) per IEC1000-4-2 Breakdown voltage : VBR = 6 V min. Low leakage current < 1 µA. 1 R 4 R D Cz C Cz D D Cz C Cz D 2 3 R R 5 BENEFITS EMI / RFI noise suppression.
