3cW7000H3/y-842a
The 3CW7000H3/Y-842A is a water cooled, ce-
ramic/metal, medium-mu power triode designed
primarily for use in industrial radio frequency
heating services. Its water cooled anode is con-
servatively rated at 7 kW of plate dissipation with
low water flow and pressure drop. The tube is a
version of the air cooled 3CX4500F3 and is recom-
mended for industrial applications where reserve
anode dissipation is required. Input of 25 kW is
permissible up to 75 MHz. Plentiful reserve emis-
sion is available from its 546 watt filament. The
grid structure is rated at 300 watts, making this
tube an excellent choice for industrial service.
