XL-DC10UYBC is a common-cathode seven-segment LED display (figure-8 or dual figure-8 segment display device) with yellow emission and black face. It features outline dimensions of 25.3×10×8 mm (1-inch digit height). Its length is 0.3 mm longer than red/yellow-green variants and identical to blue, true-green and white models.
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), moderate brightness of 195 mcd and service life exceeding 50,000 hours. It is suitable for various electronic equipment requiring yellow numeric display, and delivers outstanding performance especially in scenarios demanding high recognizability or warning effects.
