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 body is at ground potential in operation.
Note 3 :
All voltages 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
product improvement. NEC should be consulted before using this information for equipment
design. This data sheet should not be referred to a contractual specification.
