PulseGuard Suppressors Surface Mount Polymeric ESD Suppressors PGB1 Series Halogen-Free / Lead-Free Description PulseGuard ESD Suppressors help protect sensitive electronic equipment against electrostatic discharge (ESD). They supplement the on-chip protection of integrated circuitry and are best suited for low-voltage, high-speed applications where low capacitance is important. Data ports utilizing such high-speed protocols as USB 2.0, IEEE1394, HDMI and DVI can benet from this new technology. PulseGuard suppressors use polymer composite materials to suppress fast-rising ESD transients (as specied in IEC 61000-4-2), while adding virtually no capacitance to the circuit.
