📌 Product Overview
The XL-234UGC-L is a standard 3mm through-hole LED featuring a white water-clear colloid and a dominant wavelength of 520nm (Green). 💡 It is engineered to provide high luminous intensity—ranging from 900 to 1800 mcd—making it suitable for both status indication and low-level illumination.
This component is designed for general-purpose PCB assembly where reliable optical performance and long operating life are required. The design focuses on consistent light output and energy efficiency, driven by a low DC voltage.
🎯 Typical Applications
Based on the 110-degree viewing angle and robust thermal characteristics, the XL-234UGC-L fits the following scenarios:
- Consumer Electronics: Status indicators for home appliances and digital devices.
- Automotive Systems: Dashboard illumination and interior panel lights (non-critical).
- Industrial Indication: Traffic instructions and electronic clock displays.
- Medical & Education: Signal lights for beauty instruments and teaching equipment.
- Urban Lighting: Decorative lighting chains and city beautification projects.

❓ FAQ
Q: What is the forward voltage requirement for this LED?
A: The typical forward voltage is 3.0V, with a maximum of 3.4V at 20mA. Ensure your driving circuit can supply at least 3.4V to account for tolerance variations.
Q: Can this LED be used for outdoor lighting?
A: While it is used in urban lighting, the operating temperature range is -20°C to +85°C. For extreme outdoor environments, additional waterproofing and thermal management are required.
Q: What does MSL Level 2 mean for assembly?
A: Moisture Sensitivity Level 2 means the components can be exposed to the factory floor for up to one year (at <30°C/85% RH) before baking is required prior to soldering.
Q: How is the brightness sorted?
A: Brightness is sorted into grades A8 (900-1200 mcd), A9 (1200-1500 mcd), and B1 (1500-1800 mcd). Specify the required grade when placing orders to ensure consistency.
