This document introduces the features and characteristics of the BBT-AA55344RD product from Dinghao Electronics. The product is a 0.52 inch (13.2mm) high three-digit seven-segment display with continuous uniform segments, low power requirement, excellent character appearance, and solid state reliability. It uses high-efficiency red chips, black face, and white segments.
The BT-A534RD is a 13.2 mm (0.52") high three‑digit seven‑segment LED display with continuous uniform segments, low power consumption, and solid‑state reliability. It is designed for direct‑drive common anode applications and features categorized luminous intensity.
Key specifications include a digit height of 0.52 in (13.20 mm), power dissipation of 80 mW per segment, forward current of 30 mA (peak 150 mA at 1 kHz), reverse voltage of 5 V, operating temperature range from –40 °C to 80 °C, and typical forward voltage of 2.5 V at 10 mA. Optical data such as peak wavelength (640 nm) and dominant wavelength (626‑636 nm) are also provided.
