The duty cycle should not exceed 0.001. For peak currents exceeding 5.0A the product of peak current in amps and pulse duration in µs should not exceed 40 and the valve should not be operated for longer than 5µs in any 100µs interval. For peak currents not exceeding 5.0A the anode dissipation of 60W shall determine the permissible pulse length. At higher duty cycles the peak current must be reduced in proportion. In applications where the peak current drawn is less than the maximum rating, the heating-time may be reduced proportionately. In no circumstances however, should it be less than 60 secs. The screen grid decoupling series resistance must be at least 20k ohms.
