Notes (1) None of the absolute maximum ratings should be
exceeded under any circumstances even for an
instant or a transient, since to do so may cause
damage to the tube. A combination of the
maximum rating conditions can not be guaranteed.
(2) All the voltage parameters are in reference to the
cathode voltage.
(3) "Vn" is typical filament voltage for average anode
current. (see Fig. 4)
Filament voltage has to be immediately reduced
after applying the anode voltage, in accordance
with Fig 4.
(4) This condition is not drenched by water.
(5) It makes used of thermoswitch, which gives open
signal in the case of the temperature greater than
80±5℃ on the tube. Because of magnetron defends
