Three-digit 7-segment thru-hole displays integrate three numeric positions for voltage/current readouts, countdown timers, scoreboard elements, and instrumentation where 0–999 ranges are required. Each digit shares segment lines with independent strobe pins, enabling efficient multiplexed drive from a single MCU or dedicated LED driver IC.QUEENDOM 3-digit modules offer red, green, amber, and blue emission with common-anode or common-cathode pinning, digit heights from 10 mm to 25 mm, and matched luminous-intensity bins for uniform digit-to-digit appearance. Decimal points can be positioned right, left, or center per model. The black-face epoxy reduces ambient reflection for high-contrast viewing, and all parts pass 260 °C wave-solder compatibility. Full pinouts, absolute maximum ratings, and bin structures are documented in the DIP LED datasheet downloads.
