chaRacteRistics
The 3CW5000F3/8243 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 5 kW of plate dissipation with low water
flow and pressure drop. Input of 12.5 kW is per-
missible 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.
