A minimum clearance of 25 mm  must be maintained between
the magnetron and any magnetic materials.


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 2 mF 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 8C. For ambient temperatures between 0 and 755 8C, cathode
  pre-heating time is 90 seconds minimum.

4. Design test only. The maximum frequency change with anode temperature change (after warming) is
  70.25 MHz/8C.

OUTLINE DIMENSIONS

Outline Notes

1. The mating surface of the magnetron baseplate will be flat to within 0.20 mm.
2. Positional tolerance of holes +0.2 mm with respect to waveguide aperture.
