PULSE-GUARD® ESD Suppressors
Surface Mount Polymeric Electrostatic Discharge Suppressors
PGB2 0201 Series
Description
PULSE-GUARD® ESD Suppressors help protect sensitive
electronic equipment against electrostatic discharge (ESD).
They 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.
They supplement the on-chip protection of integrated
circuitry and are best suited for low-voltage, high-speed
applications where low capacitance is important to ensure
minimal interference of data signal integrity.
The new and ultra-small surface mount PGB2 0201 series
offers a RoHS Compliant, Halogen Free, and 100% Lead
Free circuit protection alternative.
