Overview
PROTECTION PRODUCTS - EMIClamp® Description The EClamp®2357NQ 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.
They have been optimized for protection of touch screen displays, secure digital (SD) card interfaces, and color 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 1.
0GHz 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.
The EClamp2357NQ is qualified to AEC-Q100 Grade 1 for Automotive use.
