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 refferred to the cathode potential except the heater voltage.
Note 4 : The optimum operating parameters are shown on atest 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.
