Littelfuse PulseGuard 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.
The PGB1 devices 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. The PGB2 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 0402 series offers a RoHS-compliant, halogen-free, and 100% lead-free circuit protection alternative.
