Description

TAF1092 is a cold-cathode numeric or character indicator tube listed in the supplied German comparison catalog as comparable to RFT type Z5740M. The catalog publishes 150 V anode striking, 140 V maintaining, 120 V extinction, a 1.5–2.5 mA cathode-current range, and associated display and mechanical data for that RFT type. The source explicitly cautions that comparable tubes are not necessarily identical, so these mapped RFT values are retained as comparison data rather than asserted as exact original-manufacturer ratings.
