- EMIClamp TM Description
The EClamp 1002A is a low pass filter array with integrated TVS diodes for ESD protection. It is designed to provide bidirectional filtering of EMI/RFI signals and electrostatic discharge (ESD) protection in portable electronic equipment. This state-of-the-art device utilizes solid-state silicon-avalanche technology for superior clamping performance and DC electrical characteristics. They have been optimized for use on a speaker port in cellular phones and other portable electronics. The EClamp1002A effectively replaces 10 discrete ponents in a small SC-89 package to provide ESD protection and EMI filtering. Each device requires less than 2.9mm2 of PCB area with a low profile of only 0.60mm. This small package will protect and filter up to two lines. This small outline makes the device especially well suited for portable applications. The TVS diodes are bidirectional for supporting bipolar audio signals without distortion. The TVS diodes provide effective suppression of ESD voltages in excess of 15k V (air discharge) and 8k V (contact...
