ECLAMP2357NQ.TLT

The ECLAMP2357NQ.TCT is an EMI Filter and ESD Protection Device for secure digital card interfaces. It 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. It has been optimized for protection of touch screen displays, secure digital (SD) card interfaces and colour LCD panels in cellular phones and other portable electronics. The device consists of six pi filter circuits comprised of TVS diodes for ESD protection and a resistor capacitor network for EMI/RFI filtering. A series resistor value of 100Ω and a component capacitance value of 10pF are used to achieve 20dB minimum attenuation from 1GHz to 3GHz. The device also includes 4 discrete TVS diodes for dedicated ESD protection. All of the TVS diodes provide effective suppression of ESD voltages in excess of ±15kV (air discharge) and ±8kV (contact discharge) per IEC 61000-4-2, level 4.
