FU-200 is a direct thermal carbonization thorium-tungsten cathode glass triode anode cooling ethod is natural cooling,the maximum anode power dissipation is 50W,the maximum operating frequency is 30MHz,the tube is mainly used for industrial high frequency heating equipment for oscillation power amplifier.NL-35TG can be produced used interchangeably.
Note:in general can be used in the matched load of work under the natural cooling, but the equipment must be ventilated in the nonmatched load,high pressure,high frequency conditions when working under forced air cooling,ventilation shuould be through the outlet from the tube at the bottom of bottom-up air supply.
