PROTECTION PRODUCTS - EMIClampTM Description The EClampTM2422N is a (C-L-C) low pass filter array with integrated TVS diodes. It is designed to suppress unwanted EMI/RFI signals and provide electrostatic discharge (ESD) protection in portable electronic equipment. This state-of-the-art device utilizes solidstate silicon-avalanche technology for superior clamping performance and DC electrical characteristics. It has been optimized for protection of headset audio ports in cellular phones and other portable electronics. The device consists of two identical circuits comprised of TVS diodes for ESD protection, and a C-L-C pi-filter for EMI/RFI filtering. A typical inductor value of 2nH and a capacitor value of 100pF are used to achieve 20dB minimum attenuation from 800MHz to 2.7GHz.
