XL-BDZ788SRBC is a common-anode red LED display device (segment/matrix type) with a black face. It features outline dimensions of 20×20×5.9 mm and delivers a larger display area than model 757.
It adopts solid potting encapsulation with advantages of compact size, light weight and excellent shock resistance.
The device can be driven at low voltage and low current, featuring ultra-short luminous response time (<0.1 μs), high brightness and service life exceeding 50,000 hours. It is suitable for electronic equipment requiring medium-size numeric display.
