XL-DC10UBBC is a common-cathode seven-segment LED display (figure-8 or dual figure-8 segment display device) with blue emission and black face. Its outline dimension is 25.3×10×8 mm (1-inch digit height, 0.3 mm longer than red/yellow-green variants).
It adopts solid potting encapsulation, featuring compact size, light weight and excellent shock resistance.
The device can be driven at low voltage and low current, with ultra-short luminous response time (<0.1 μs), high brightness and service life exceeding 50,000 hours. It is suitable for all types of electronic equipment requiring blue numeric display.
