About the ITL 25-1
The ITL 25-1 is a power triode manufactured by Thomson / Thales. Thales high-power ITL series air-cooled metal-ceramic triode for high-capacity industrial RF dielectric heating and oscillator systems.
Key ratings of the ITL 25-1 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 and industrial manufacturing. Notable features: high-power ITL series, air-cooled convenience, 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.
PartnerTubes supplies the ITL 25-1 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.
