XL-DC10SRBC is a common-cathode seven-segment LED display (non dot-matrix, figure-8 or dual figure-8 segment display device) with red emission and black face. It has outline dimensions of 25×10×8 mm (1-inch digit height).
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 various electronic equipment requiring numeric display.

Usage Recommendations
Constant-current drive is recommended. Current-limiting resistors shall be connected in series for each segment and decimal point.
For dynamic scanning operation, the average current is 4~5 mA and the peak current shall not exceed 100 mA.
ESD protection and moisture prevention should be observed during application.
