4CPW100KA Datasheet, PDF (1/1 Pages) Communications & Power Industries, Inc. – Pulse modulator

4CPW100KA/Y-841
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 rug-
ged 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 dissi-
pation of 100 kilowatts. Available accessories are
a tube support plate, an air system socket, and
containment hood for protective atmosphere.
