GENERAL DESCRIPTION itran® DG12C numerical indicator tubes provide a highly efficient display of digits and characters at extremely low operating voltages. These single-plane tube read-outs offer low power consumption with rugged construction, and an exceptionally wide viewing angle with unsurpassed brightness and clarity. The numerical figures, mathematical symbols and characters are composed of highly efficient green phosphor-coated segments, energized by electrons emitted from a direct heated super fine cathode. Particularly suited to decimally coded applications such as basic counters and computer circuits fren DG12C indication tubes display decimal points, prime, and numerical figures "0" through "9", e@ Uni-Plane Design : e Low Voltage e Sharp, Bright Green Characters e Low Power Consumption ELECTRICAL CHARACTERISTICS Cathode Direct heating Heater current 95mA Heater voltage at 95mA 0.85 Volts +10% Color of figures Green Brightness 80 Foot-lamberts ABSOLUTE MAXIMUM RATINGS Maximum voltage, phosphor segments 27 Volts Maximum pulse voltage upon phosphor segments 50 Volts Minimum voltage, phosphor segments , -27 Volts Maximum screen grid (control grid) 25 Volts Maximum pulse voltage upon screen grid (control grid) 30 Volts Minimum screen grid (control grid) -30 Volts Maximum heater current 105 mA AVERAGE RATINGS Cathode current (at 25 Volts of phosphor segment and grid voltage) 10mA Numerical phosphor segments current ImA Current to each symbol, "9" and "9" 0.2mA Ambient temperature -40 to +70°C (12) TYPICAL OPERATION te Voltage, phosphor segments 25 Volts (6) c Screen grid (control grid) 20 Volts N.C Screen grid (control grid) cut off voltage -4 Volts Phosphor segments cut off voltage 0 Volts S) @ BOTTOM VIEW MECHANICAL DESIGN EXTERNAL DIMENSIONS Overall Length 53mm Diameter of glass tube 13mm Maximum viewing angle 120 degree Net weight 8.2a9r Mounting position Optional Base cf. drawings CHARACTER DIMENSIONS Numericals Height: 10.8 mm, Width: 7.2 mm Decimal point Diameter:1, 4 mm Prime : Height: 2. 55mm, Width: 1.3 mm CHARACTER OUTLINES (actual size) =! —, | “ ric) Greer fod OUTLINE DRAWING x < s le-13¢ MA X>4 S 4.06 MAX 8.0+0.2 J " 9 = Le) | i | ; rr) x i <i ae | ee > < ot bth 3 ap LEAD DIAMETER 7.4¢LEAD CIRCLE Unit :mm For further information and prices, please contact:
