Brief introduction
ITL 12-1 forced air cooled triode
Product description
ITL 12-1 air-cooled triode electron emission tube
ITL 12-1 wind Cold triode electron emission ITL 12-1 This type of electronic tube can be a metal ceramic coaxial structure, a thorium tungsten cathode, and a forced air cooling triode, with a working frequency of 120MHz, anode dissipation of 12kW, output power of continuous 33kW, and pulse operation of 50kW. It is mainly used for industrial high-frequency heating, pulse oscillator, and can be interchanged with 3C X10000D3 Toshiba 1TL12-1 electronic tube produced by Eimac Company in the United States.
