The 3CW5000F3/8243 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 5 kW of plate dissipation with low water flow and pressure drop. Input of 12.5 kW is permissible up to 30 MHz. Plentiful reserve emission is available from its 375 watt filament. The grid structure is rated at 150 watts, making this tube an excellent choice for industrial service.
