The 3CW30,000H3 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 30 kW of plate dissipation with low water
flow and pressure drop. Input of 60 kW is permis-
sible up to 90 MHz. Plentiful reserve emission
is available from its 1000 watt filament. The grid
structure is rated at 500 watts, making this tube
an excellent choice for industrial service.
