The 4CPW100KA/Y-841 is a ceramic/metal, water cooled, high power tetrode intended for use as a pulse modulator or in regulator service. Its rugged mesh thoriated-tungsten filament provides ample emission for 100 amp peak current rating. The 4CPW100KA/Y-841 is rated at 110 kilovolts in a protective atmosphere or with oil immersion between the anode and screen grid terminal. The water-cooled anode is rated for a maximum dissipation of 100 kilowatts. Available accessories are a tube support plate, an air system socket, and containment hood for protective atmosphere.
