EClamp2378K
Description
The EClamp TM2378K is a 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. They have been optimized for protection of color LCD panels in cellular phones and other portable electronics.
The device consists of eight identical circuits prised of TVS diodes for ESD protection, and a resistor capacitor network for EMI/RFI filtering. A series resistor value of 100Ω and a capacitance value of 10p F are used to achieve 30d B minimum attenuation from 1.8GHz to 2.5GHz. The TVS diodes provide effective suppression of ESD voltages in excess of ±15k V (air discharge) and ±8k V (contact discharge) per IEC 61000-4-2, level 4.
The EClamp2378K is in a 16-pin, Ro HS/WEEE pliant, SLP3313P16 package. It measures 3.3 x...
