Electron tube is a rugged high-mu power triode, designed with beam-forming cathode and control grid geometry to allow the simplicity of design and circuit advantages of a triode with the gain of a tetrode. The tube is intended for pulse modulator or pulse regulator service. The external anode may be forced-air cooled. Or, for increased high voltage holdoff, the tube may be immersed in an insulating liquid, which is also used to cool the tube. This tube may be used in a grid or plate pulsed RF application where the high peak power is required.
Electrical parameters Filament voltage: 10V Filament current: 9.9A The maximum instantaneous filament current: 15A Magnification factor: 28 Transconductance: 4.5mA / V Electrode capacitance: Anode - the GRID: 8pF Cathode - the GRID: 11pF Anode - Cathode: ≤ 0.35pF Mechanical properties: Weight: 0.42Kg Installation: vertical, anode terminals up Cooling: cooling Shell and tube maximum temperature: 225 ° C Sealing at the highest temperature: 220 °C Leads to the end of the maximum temperature of 180 °C Maximum ratings
The maximum anode DC voltage: 4KV Maximum Anode DC Current: 535mA Maximum GRID DC current: 115mA Maximum anode dissipation power: 450W Maximum GRID power dissipation: 50W Maximum anode input power: 2.2KW In typical operation: class C telegraph Filament voltage: 10V Anode DC voltage: 4KV GRID DC bias voltage:-350V Anode DC Current: 535mA GRID DC current: 115mA Anode output power: 1.69KW Note: generally under matched load can be naturally cooled, but the equipment must be well ventilated, if in a non-matched load, high pressure, high-frequency conditions required for forced air cooling, ventilation should be through the outlet from the tube at the bottom of under the previous air.
