3CW40,000H3
The 3CW40,000H3 is a water cooled, ceramic/
metal, medium-mu power triode designed primar-
ily for use in industrial radio frequency heating
services. Its water cooled anode is conservatively
rated at 40 kW of plate dissipation with low water
flow and pressure drop. Input of 100 kW is per-
missible up to 90 MHz. Plentiful reserve emission
is available from its 1600 watt filament. The grid
structure is rated at 800 watts, making this tube
an excellent choice for industrial service.
