PULSE-GUARD® ESD Suppressors
Surface Mount Polymeric Electrostatic Discharge Suppressors
Description
PULSE-GUARD 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.
PULSE-GUARD 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.
Features
