The 3CW150,000H3 is a water cooled, ceramic/ metal, medium-mu power triode designed primarily for use in industrial radio frequency heating services. Its water cooled anode is conservatively rated at 150 kW of plate dissipation with low water flow and pressure drop. Input of 320 kW is permissible up to 30 MHz. Plentiful reserve emission is available from its 310 watt filament. The grid structure is rated at 1500 watts, making this tube an excellent choice for industrial service.
