Ise Electronics Itron DG-19 Numerical Indicator Tube Datasheet (February 1968)

GENERAL DESCRIPTION 4 ltron®) DG-19 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, Itroné) DG-~19 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 95 @mnA Heater voltage at Sowa 75mA 1.6 Volts 10% Color of figures Green Brightness 80 Foot-lamberts ABSOLUTE MAXIMUM RATINGS Pulse Voltage Upon } Max. 30 Volts Screen and Control Grids Min. —30 Volts Maximum voltage, phosphor segments 27 Volts Minimum voltage, phosphor segments -27 Volts Maximum screen grid (control grid) 25 SP Volts Minimum screen grid (control grid) -27 Volts Maximum heater current 100 mA Maximum Pulse Voltage upon phosphor segments 50 Volts (This is based on aging performed at 50 volts) AVERAGE RATINGS Cathode current (at 25 Volts of phosphor segment and grid voltage) 10mA Numerical phosphor segments current 1mA Current to each symbol, "'" and "9" 0.2mA Ambient temperature -40 to +3gmg 70°C TYPICAL OPERATION Voltage, phosphor segments 25 Volts Screen grid (control grid) 20 SESSS=Volts Screen grid cut off voltage -4 Volts Phosphor segments cut off voltage 0 Volts BOTTOM VIEW MECHANICAL DESIGN EXTERNAL DIMENSIONS CHARACTER DIMENSIONS Overall Length 53mm ; Diameter of glass tube 19mm Numerials Height: 14,0mm, Maximum viewing angle 120 degree Width: 9.8mm Net weight 10.0 gr Decimal point Diameter: 2.0mm Mounting position Optional Prime Height: 3.5mm, Base cf. drawings Width: 1.6mm CHARACTER OUTLINES (actual size) mr} f JfA4f58 J r oo" LJ 4 a ie eee 7 OUTLINE DRAWING 19.0% max.
