Description

NEC side-view cold-cathode display-discharge tube showing digits 0-9 and decimal point. It has an approximate 10 mm display height. The catalog gives a 190 V minimum anode supply and 5–9 mA peak cathode current for the main display. Termination/socket information is Wire-leaded. Pulse-operated high-brightness miniature display tube; table currents are peak cathode currents.
