Note 1 : Absolute rating should not be exceeded under continuous or transient conditions. A single absolute
rating may be the limitation and simultaneous operation at more than one absolute rating may not be
possible.
Note 2 : The tube helix is at the ground potential in operation.
Note 3 : All voltages except heater voltage are referred to the cathode potential except the heater voltage.
Note 4 : The optimum operating parameters are shown on a test performance sheet for each tube.
Note 5 : These characteristics and operating values may be changed as a result of additional information or prod-
uct improvement. NEC should be consulted before using this information for equipment design.
This data sheet should not be referred to a contractual specification.
