The 4CPW1000KB is a water cooled power tetrode intended for use as a pulse modulator or pulse regulator. The tube is rated for 175 kVdc holdoff in a protective atmosphere, with a 75 ampere pulse cathode current rating during conduction and 1000 kilowatt anode dissipation rating (average during the pulse). Peak anode current capability in excess of 100 amperes for short pulse operation is practical. Class of Operation Characteristics Plate Dissipation (Max.) Screen Dissipation (Max.)
