The 4CPW10,000R/9016 is intended for use as a pulse modulator or regulator for use with magnetrons, crossed field amplifiers, TWTs, klystrons, and other RF power sources. The inherent constant current characteristic of this tetrode is well suited for series switching of plasma discharge devices, electron beam welding equipment , etc. The rugged construction of this tube allows it to be used under demanding vibration and shock conditions. The holdoff voltage rating is 25 kVdc in pulse modulator or regulator service, with a peak anode current of 24 amperes. Class of Operation --- Characteristics Plate Dissipation (Max.)
