RF Power Triode BW1608J2F
BW1608J2F is a water cooled, metal /
ceramic power triode. It uses a thoriated
tungsten filament and a coaxial structure,
intended for use in industrial radio frequency
heating as oscillator. Max. frequency:
30MHZ, max plate dissipation: 50KW.
Output power (class C oscillator, less
driver): 118 kw
