About the 3CX10000H3
The 3CX10000H3 is a power triode manufactured by Eimac / CPI. Very high-power ceramic triode with 10 kW plate dissipation for high-power FM broadcast transmitters and scientific RF power sources.
Key ratings of the 3CX10000H3 include tube type Triode, plate dissipation 10000 W, max plate voltage 12 kV, max plate current 3.5 A, mu 200 and max frequency 200 MHz.
Typical applications are high-power FM broadcast 100–250 kW, shortwave broadcast transmitters, high-power particle accelerator RF and scientific plasma systems. Notable features: 10 kW plate dissipation, water-cooled high power, high mu 200 triode and continuous broadcast duty rating.
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.
