A minimum clearance of 25 mm must be maintained betweenthe 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. 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.

 

4. Design test only. The maximum frequency change with anode temperature change (after warming) is -0.25 MHz/8C.
