pF max

A minimum clearance of 25mm 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 2 mF

  may be necessary depending on the equipment design. For further details see the Magnetron Preamble.

 

2. For ambient temperatures above 0℃. For ambient temperatures between 0 and -55℃, cathode pre-

  heating time is 45 seconds minimum.

OUTLINE NOTES

1. Positional tolerance 0.4 mm diameter

2. The mating surface of the magnetron baseplate will be flat to within 0.2 mm.
