XL-234UGC-L LED: Bin Selection & Thermal Integration Guide

📌 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.

📊 Key Technical Specifications

The following table outlines the electro-optical characteristics under standard test conditions (Ta=25°C, IF=20mA).

Soldering Limits:

  • Wave Soldering: Max 240°C for ≤6s.
  • Manual Welding: Max 300°C for ≤3s.
  • 🔒 Critical: The soldering point must be >2.0mm from the colloid base to prevent thermal damage.

📦 Package, Dimensions & Assembly Notes

  • Package Type: 3mm Radial Lead (Long leg).
  • Dimensions: 3.0 (W) x 2.0 (T) x 4.0 (H) x 28 (L) mm.
  • Moisture Sensitivity: MSL Level 2.
  • Packaging: 1000 PCS per anti-electrostatic foil bag.

Assembly Advice: The component complies with EIA standard packaging, facilitating automated feeder systems. Ensure the storage environment remains below 30°C and 70% RH to prevent moisture ingress prior to assembly.

🚀 Sourcing & Supply Considerations

  • Binning Control: Verify brightness and voltage bins with the supplier if uniformity is critical for the application.
  • Authenticity: Source through XINGLIGHT authorized channels to guarantee RoHS compliance and reliability standards.
  • Supply Chain: Standard packaging allows for quick integration into existing CEM workflows without custom feeder adjustments.

❓ 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.
