Caution for the use:
- While move and install the Electron Tube, should be put very carefully, strong vibration and been struck is forbidden.
- Electron Tube should be stored in the dry place, the temperature should above -5ºC. For long-term preservation, it should be better sealed in plastic bags and put some dry desiccant in. The filament voltage should be accurate measured, the variation should not beyond 2%(<2%).
- Must turn on the cooling system before set up an electric circuit. It should keep turn on the cooling system for 15 minutes after power off. The dust in the cooling air duct system should be cleaned up regularly. The water should keep good quality.
- The filament should preheat 30 minutes. The preheat time should be more than 60 minutes for the long-term been storage Electron Tube and first time used Electron Tubes.
7T85RB/FU-947F, it is metal ceramic structure, carbonization thorium tungsten cathode triode, cooled by forced air. The max working frequency 110MHz, the max anode dissipation power 2.5kW, the max anode output power 5.1kW, the tube is mainly used as the oscillator in industrial high frequency heating equipments.
