Nos tubes, made in USSR (Russia), items is new, old stock.
IV-22 (ИВ-22) – 7 segment display luminescent green color glow. Indicator IV-22 is in a glass flask with a rigid leads. Display through the dome tank. Anodes device in the form of seven segments and a decimal point.
Key Features LED IV-22:
These 7-segment tubes display digits (0 to 9), some characters and decimal point.
Brightness > 250 cd / m ²
Filament voltage 1,2 V (1,0 - 1,32) V
Filament current 100 mA (80 - 115) mA
Anode voltage 27 V (22 - 30) V
Grid voltage 27 V (22 - 30) V
Anode segments (total) (2.5 .. 6) mA
Grid current <12mA
Operating time > 5000 hours
Size of the tube (32 x 22 x 27) mm, (1,26 x 0,866 x 1,063) in
Character height 18 mm (0,701 in)
Character width 12 mm (0,472 in)
Notes:
To eliminate the flicker frequency of the supply voltage of the anode and the grid must be at least 40 Hz. In pulse mode voltage anode segments and the grid can be up to 80 V. To avoid possible voltage backlight off segment should not exceed (1.5-2.0) V.
No vorking segments should be connected to ground through a resistor circuit is not more than 510 kOhm.
