About the RS 3021CJ
The RS 3021CJ is a power triode manufactured by Thomson / Thales. Thales RS 3021 Plus (RS 3021CJ) water-cooled metal-ceramic triode for high-power RF end stage applications in industrial CO₂ laser and RF heating systems.
Key ratings of the RS 3021CJ include tube type Triode, construction Metal-ceramic, anode cooling Water, cathode Thorium tungsten and max frequency 100 MHz.
Typical applications are CO₂ laser cutting machine end stage, industrial high-power RF heating, induction heating, large RF generators and industrial applications. Notable features: RS 3021 Plus high-power design, water-cooled anode, metal-ceramic construction and thomson/Thales quality.
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.
