Electrical And Physical Characteristics:

All ratings given in this data sheet a reab solute, nonsimultaneous ratings. It is the equipment designer’s responsibility to
ensure that they are not exceeded. The spark gap life depends on circuit conditions such as peak discharge current and
duration, charge transfer per discharge and the repetition rate.
