The convenient physical size of the Milli-Arc series of spark gaps and their 10,000 ampere (8 x 20 usec waveshape) discharge capability make this series the most suitable for general purpose transient protection. They also may be used for energy release in exploding bridgewire applications and in various vacuum tube grid circuits for tube arc protection. Insulation resistance is greater than 109ohms and capacitance is less than 2 pF. Milli-Arc tubes are available in breakdown voltages from 90 to 4500 volts (MLH), 8500 volts (MLF). Units normally stocked are as follows. Other breakdown voltages available on request.
