EClamp2465T Low Capacitance ESD/EMI Protection for SIM Card TM PPROTECTION PRODUCTS - EMIClampROTECTION PRODUCTS PRELIMINARY Features Description TM The EClamp 2465T is a combination EMI filter and line Bidirectional EMI/RFI filter with integrated TVS termination device with integrated TVS diodes for use on for ESD protection SIM Card interfaces on cellular phones and other por- ESD protection to IEC 61000-4-2 (ESD) Level 4, table electronics. This state-of-the-art device utilizes 15kV (air), 8kV (contact) solid-state silicon-avalanche technology for superior TVS working voltage: 5V clamping performance and DC electrical characteristics. Termination Resistors: 100 Ohms & 47 Ohms Capacitance: 10pF (Typical at VR = 0V) The device consists of three circuits that include series Protection and filtering for four lines impedance matching resistors for proper termination of Solid-state technology the SIM card interface. Termination resistor value of 100 Ohms is included on the Reset and Data lines and 47 Ohms on the CLK line. TVS diodes are also included Mechanical Characteristics on each line for ESD protection in excess of 15kV (air SLP1713P8T 8-pin package discharge) and 8kV (contact discharge) per IEC 61000- 4-2, level 4. An additional TVS diode connection is RoHS/WEEE Compliant included for protection of the voltage (Vcc) bus. Nominal Dimensions: 1.7 x 1.3 x 0.40 mm Lead Pitch: 0.4mm The EClamp2465T is in a 8-pin, RoHS/WEEE compliant, Lead finish: NiPdAu SLP1713P8T package. It measures 1.7 x 1.3 mm with Marking: Marking Code + Date Code a nominal height of only 0.4mm. The leads are spaced Packaging: Tape and Reel at a pitch of 0.4mm and are finished with lead-free NiPdAu. The small package makes it ideal for use in Applications portable electronics such as cell phones and digital still cameras.
