The 4CPL1000B tube is designed for switch tube, pulse modulator, or voltage regulator service. It will pass anode current up to 8 amperes for pulses up to 100 microseconds duration, and derated values of anode current at longer pulse durations. This tube is designed for immersion in cooling a liquid dielectric and can dissipate 1,000 watts. In air with proper cooling, plate dissipatin is 300 watts. The 4CPL1000B has a special support for environmental stess absorption. This tube is rated to operate at an anode potential up to 15 kVdc when immersed in the recommended coolant. When immersed, the rating is not altitude dependant. Class of Operation Characteristics Plate Dissipation (Max.) Screen Dissipation (Max.) Grid Dissipation (Max.)
