7062
7062 is also designated E180CC. Completed sales put the typical price at $41.50 per tube.
The 7062 is a special quality double triode with separate cathode connections, designed for application in electronic computer circuits. It employs a coated, unipotential cathode and is housed in a T6 1/2 envelope with an E9-1 base.
Ratings
The heater may be operated in series at 12.6 volts and 200 mA, or in parallel at 6.3 volts and 400 mA; the parallel heater voltage rating is 6.3 volts ±5%. The maximum bulb temperature is 170 degrees Celsius. Per section, the maximum plate voltage is 275 volts, and the maximum plate dissipation is 2 watts. The maximum plate voltage without current is 600 volts. The maximum negative grid voltage is 100 volts, and the maximum grid current is 2 mA. The maximum peak grid current is 50 mA, and the maximum peak cathode current is 200 mA, each with a pulse time of maximum 10 microseconds at a duty cycle of 1%. The maximum grid circuit resistance is 1 megohm with automatic bias and 0.5 megohm with fixed bias.
Typical Characteristics
At a plate voltage of 100 volts and a grid voltage of −0.8 volts, the typical plate current is 8.5 mA; at a plate voltage of 150 volts and a grid voltage of −1.85 volts, the typical plate current is 17.8 mA. Typical transconductance is 7800 micromhos, typical amplification factor is 50, and typical internal resistance is 6400 ohms.
Capacitance
Typical capacitances for triode No. 1 are 0.5 pF plate-to-cathode-and-heater, 3.5 pF grid-to-cathode-and-heater, and 2.2 pF plate-to-grid. Typical cathode-to-heater capacitance is 3.5 pF. Maximum inter-triode capacitances are 1.3 pF plate-to-plate and 0.06 pF grid-to-grid.
Application Notes
The 7062 is not intended for use in circuits critical as to hum, microphony, and noise. The datasheet is dated 19.1.1959.
