About the ITL 3-1
The ITL 3-1 is a power triode manufactured by Thomson / Thales. Thales ITL series air-cooled metal-ceramic triode for low-to-medium power industrial RF heating, dielectric heating, and oscillator applications.
Key ratings of the ITL 3-1 include tube type Triode, construction Metal-ceramic coaxial, cooling Forced air, cathode Thorium tungsten and max frequency 120 MHz.
Typical applications are industrial RF dielectric heating, plastic welding, wood gluing, low-power RF oscillators and industrial high-frequency generators. Notable features: ITL series air-cooled design, metal-ceramic coaxial, thorium tungsten cathode and forced air cooling.
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.
PartnerTubes supplies the ITL 3-1 worldwide from Groningen, the Netherlands — availability, lead time and price are confirmed per enquiry. Our team can help with equivalent and cross-reference types, sockets and accessories, and supply programmes for OEM and maintenance customers. Interchangeability must always be confirmed for the specific equipment.
