5920

5920 is also designated E90CC.

Description

The 5920 is a twin-triode amplifier tube of the heater type, usable with AC or DC heating. It is housed in a T 5 1/2 miniature envelope with a maximum body length of 2 3/8 inches and uses a miniature button 7-pin base.

Ratings

Per section, the 5920 has a maximum plate voltage of 300 volts, a maximum plate dissipation of 2 watts, and a maximum cathode current of 15 mA. The maximum heater-cathode voltage is 100 volts. The heater requires 6.3 volts at 0.4 ampere.

Electrical Characteristics

At a plate voltage of 100 volts and a grid voltage of -1.8 volts, the 5920 exhibits an amplification factor of 25, a transconductance of 5500 micromhos, and a plate current of 0.5 mA. For each section, the direct interelectrode grid-to-plate capacitance is 2.6 uuf, the grid-to-cathode capacitance is 3.1 uuf, and the plate-to-cathode capacitance is 0.3 uuf; these values are approximate with no external shield.

Life

The Amperex datasheet guarantees an average life of 10,000 hours per tube, provided maximum ratings are not exceeded.

Equivalence is asserted only where the archive's own literature states it directly, in at least 40 separate documents. Tubes that merely substitute in some circuits are not listed here.
