Protection and filtering for four lines The device consists of four identical circuits comprised Solid-state technology of TVS diodes for ESD protection, and a 3-pole induc- Mechanical Characteristics tor - capacitor network for EMI/RFI filtering. A typical inductor value of 17nH and a capacitor value of 12pF SLP1713P8 8-pin package are used to achieve 20dB minimum attenuation from Pb-Free, Halogen Free, RoHS/WEEE Compliant 800MHz to 2.7GHz. The TVS diodes provide effective Nominal Dimensions: 1.7 x 1.3 x 0.50mm suppression of ESD voltages in excess of 15kV (air Lead Pitch: 0.4mm discharge) and 8kV (contact discharge) per IEC Lead finish: NiPdAu 61000-4-2, level 4. Marking : Marking Code and Date Code Packaging : Tape and Reel The EClamp2504K is in a 8-pin, SLP1713P8 package. It measures 1.7 x 1.3 x 0.50mm. The leads are Applications spaced at a pitch of 0.4mm and are finished with lead- Color LCD Protection free NiPdAu. The small package makes it ideal for use Cell Phone CCD Camera Lines in portable electronics such as cell phones, digital still Clamshell Cell Phones cameras, and PDAs.
