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 benefit from this new technology.
PulseGuard suppressors use polymer composite materials
to suppress fast-rising ESD transients (as specified in IEC
61000-4-2), while adding virtually no capacitance to the
circuit.
