Notes

1. For optimum performance a value of 6.3 V is recommended. However, this magnetron
  will work satisfactorily within the specified limits.
  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 45 seconds minimum.
4. Design test only. The maximum frequency change with
  anode temperature change (after warming) is -0.25 MHz/℃.

 

* MG5436 Anode voltage (peak) = 8.0 kV
  MG5437 Anode voltage (peak) = 8.4 kV
