📌 Product Overview
The XL-234UWC-L is a 3mm through-hole LED manufactured by XINGLIGHT, characterized by a long-legged radial structure suitable for PCB mounting. 💡 It emits a high-intensity cool white light (typical 2000 mcd) with a color temperature of 10,000K, making it ideal for applications requiring sharp, bright visibility.
👇 This component is designed for general indication and backlighting. Its water-clear colloid and wide 110-degree viewing angle ensure uniform light distribution. Designers should note the low voltage DC drive requirement, which simplifies power supply design in consumer electronics and industrial indicators.
🔌 Typical Applications
Based on the XL-234UWC-L’s 10,000K cool white temperature and durable 3mm package, the following applications are recommended:
- Status Indicators: Home appliances and digital communication devices.
- Automotive Electronics: Interior dashboard lighting and accessory indicators.
- Consumer Electronics: Electronic toys, clocks, and teaching equipment.
- Decorative Lighting: Urban lighting projects and accent fixtures.
- Instrumentation: Medical beauty instruments and traffic instruction displays.

💡 Assembly Advice: Ensure the solder joint maintains a minimum distance of 2.0mm from the epoxy body to prevent thermal damage during wave soldering processes.
🚀 Sourcing & Supply Considerations
- Binning Availability: Verify stock availability for specific brightness (B1/B2/B3) and voltage (N13) bins to ensure consistency in your BOM.
- Authenticity: Source through XINGLIGHT authorized channels to avoid counterfeit components with inconsistent color temperatures.
- Sample Support: Request engineering samples for validation of the 10,000K color temperature in your specific optical environment.
- Lead Time: EIA standard packaging usually allows for faster logistics, but confirm stock for high-volume orders.
❓ FAQ
Q: What is the forward voltage requirement for the XL-234UWC-L? A: The typical forward voltage is 3.0V, with a maximum of 3.4V at 20mA. Designers should account for the N13-3 (2.8-3.0V) to N13-5 (3.2-3.4V) binning range when designing driver circuits.
Q: Is this LED suitable for high-temperature environments? A: Yes, the XL-234UWC-L has an operating temperature range of -20°C to +85°C and has passed 1000-hour high-temperature storage tests at 85°C.
Q: What are the soldering guidelines to prevent damage? A: Do not solder within 2.0mm of the colloid bottom. For manual welding, limit exposure to 300°C for 3 seconds; for wave soldering, limit to 240°C for 6 seconds.
Q: How is the brightness graded for this model? A: Luminous intensity is graded into three bins: B1 (1500-1800 mcd), B2 (1800-2100 mcd), and B3 (2100-2500 mcd). Selecting a specific bin ensures visual uniformity in your final product.
Q: What is the Moisture Sensitivity Level (MSL)? A: The XL-234UWC-L is classified as MSL 2. Components must be mounted within 1 year of opening the sealed moisture-proof bag, or baking may be required prior to soldering.
