XL-DC10UWBC is a common-cathode seven-segment LED display (figure-8 or dual figure-8 segment display device) with white emission and black face. It features outline dimensions of 25.3×10×8 mm (1-inch digit height, identical to blue and true-green 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), high brightness (typical luminous flux of 20 lm) and service life exceeding 50,000 hours. It emits neutral white light with a color temperature of 6000~7500K and color rendering index Ra≥80, suitable for white numeric display applications requiring high brightness and authentic color reproduction.

Color Temperature (TC): 6000~7500K
Color Rendering Index (Ra): 80~85, excellent color reproduction
Full Width at Half Maximum (Δλ): 50 nm
Electrical Parameters (Ta=25℃)
Maximum Power Dissipation (Pd): 70 mW
Maximum Continuous Forward Current (IF): 20 mA
Maximum Pulse Peak Forward Current (IFP): 80 mA
Maximum Reverse Voltage (VR): 5 V
Forward Voltage (VF): 3.0~3.6 V
Reverse Current (IR): ≤20 μA
Structure & Reliability
Common cathode configuration
Operating Temperature: -30℃ ~ +70℃

Soldering Conditions: Wave soldering ≤240℃ for ≤3 s; manual soldering <250℃
Solid potting encapsulation, vibration-resistant and highly stable
Supports continuous scanning drive with wide viewing angle
Important Usage Notes
ESD protection measures must be implemented
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.
White LEDs are temperature-sensitive; thermal design should be considered.
