About the RS 3500CJ
The RS 3500CJ is a power triode manufactured by Thomson / Thales. Thales RS 3500CJ water-cooled metal-ceramic triode at the top end of the RS series for continuous heavy-duty RF power in the largest industrial generators.
Key ratings of the RS 3500CJ include tube type Triode, construction Metal-ceramic, anode cooling Water, cathode Thorium tungsten and max frequency 100 MHz.
Typical applications are ultra-high power RF generators, large-scale induction heating, continuous duty industrial RF and mega-watt class heating systems. Notable features: top-tier RS series triode, water-cooled anode, metal-ceramic construction and continuous heavy-duty operation.
Power triodes are three-electrode grid tubes used as RF oscillators and amplifiers in industrial RF heating (plastic welding, induction heating, drying), RF-excited CO₂ lasers, broadcast transmitters and particle accelerators. In oscillator service they work with vacuum capacitors in the tank and matching circuits.
