Surface Mount Polymeric ESD Suppressors

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.
