DESCRIPTION
SRC Devices 2 electrode high voltage CG3 Comgaps (1.0 - 8.5 kV) are designed for surge protection in applications for which
bias voltages or signal levels of several hundred volts are normally present. Comgaps function as switches which dissipate
a minimum amount of energy and therefore handle currents that far surpass other types of transient voltage protection.
