A minimum clearance of 5 mm must be
maintained between the magnetron and
any magnetic materials.

NOTES

1. No reduction of heater voltage is required at any value of mean input power.
  For optimum performance a value within the specified ratings must be maintained.
  The magnetron heater must be protected against arcing by the use of a minimum
  capacitance of 4000 pF shunted across the heater directly at the input terminals;
  in some cases a capacitance as high as 2mF may be necessary depending on the
  equipment design. For further details see the Magnetron Preamble.


2. Measured with heater voltage of 6.3 V and no anode input power, the heater
  current limits are 0.5 A minimum, 0.6 A maximum.


3. For ambient temperatures above 0 ℃. For ambient temperatures between
  0 and -55 ℃, cathode pre-heating time is 75 seconds minimum.
