About the ITL 25-3
The ITL 25-3 is a power triode manufactured by Thomson / Thales. Thales ITL 25 series air-cooled metal-ceramic triode, variant of the ITL 25-1 for high-capacity industrial RF applications.
Key ratings of the ITL 25-3 include tube type Triode, construction Metal-ceramic coaxial, cooling Forced air, cathode Thorium tungsten and max frequency 100 MHz.
Typical applications are industrial RF dielectric heating, high-power RF oscillators, plastic welding, industrial manufacturing and RF induction heating. Notable features: ITL 25 series variant, air-cooled design, metal-ceramic coaxial and thorium tungsten cathode.
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.
