| HIGH ENERGY SPARK GAP DEVICES TG Legacy Series DESCRIPTION CP Clare's TG Legacy Series of two electrode sparkgaps excel in applications that require the efficient transfer of high voltage, high energy pulses and DC overvoltage protection for magnetrons, diodes, capacitors, etc. The TG Legacy Series also includes three electrode triggered sparkgaps (cold cathode thyratrons) for switching high levels of stored energy in fractions of a microsecond, on command, using low energy control pulses. FEATURES s Tight DC breakdown voltage tolerance ( 10%) s Long-life tungsten or molybdenum electrodes s Rugged ceramic-to-metal or glass-to-metal s s s s APPLICATIONS Test equipment Video displays Pulse generators Medical electronics construction VOLTAGE RANGES Series DC Breakdown Voltage TG Two Electrode TG Three Electrode (See detailed specifications for more data.

The "initial" range specifies at what increasing voltage the gap begins to fire and the "rep" range specifies at what decreasing voltage the gap ceases to fire repetitively. (4) Pulse repetition rate is 1500pps instead of the standard 400pps. (5) Though outlines 2, 3, and 3A are identical, the electrode materials and configurations vary internally. (6) Though outlines 4 and 4A are identical, gaps with outline 4A have heavier internal construction to withstand more severe shock and vibration.
