3CW20,000H3

      The 3CW20,000H3 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 20 kW of plate dissipation with low water flow and pressure drop. Input of 40 kW is permissible up to 90 MHz. Plentiful reserve emission is available from its 750 watt filament. The grid structure is rated at 250 watts, making this tube an excellent choice for industrial service.
