PROTECTION PRODUCTS - EMIClampTM
Description
The EClampTM2357N 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.
