OverviewOverview

ESD Suppressors are specifically designed to protect sensitive equipment against the threat of ESD Suppressors are specifically designed to protect sensitive equipment against the threat of electrostatic discharge (ESD) and are well suited for high speed applications where low electrostatic discharge (ESD) and are well suited for high speed applications where low capacitance is needed. Switches in Antenna and data porting devices utilizing such high speed capacitance is needed. Switches in Antenna and data porting devices utilizing such high speed protocols as USB 2.0 can benefit from protocols as USB 2.0 can benefit from ESD SuppressorESD Suppressor..
