📌 Product Overview
The XL-234SYGC-L from XINGLIGHT is a 3mm through-hole LED designed for reliable status indication and general illumination. 💡 It features a standard water-clear epoxy lens with a yellow-green light output, making it suitable for front-panel interfaces and signal devices. The component utilizes a diffuse radial package with a 110-degree viewing angle, ensuring visibility from wide positions in dashboard or indicator light assemblies.
Engineers should focus on the unit's voltage grading and luminous intensity consistency when integrating this part into power-sensitive circuits. With a low forward voltage requirement (Max 2.6V) and robust thermal performance up to 85°C, this model serves as a cost-effective solution for high-volume consumer goods and industrial automation systems.
🚀 Typical Applications
Based on the electrical characteristics and 3mm form factor, the XL-234SYGC-L is optimized for the following scenarios:
- Industrial & Consumer Indicators: Status lights for home appliances, power supplies, and office equipment.
- Automotive Electronics: Interior dashboard lighting and non-critical signal indicators (subject to AEC qualification).
- Communication & Digital Devices: Router status LEDs, modem activity lights, and display backlighting.
- Signage & Instruction: Traffic instruction panels and urban lighting matrices requiring wide-angle visibility.
- Instrumentation: Electronic teaching equipment and medical beauty instrument interfaces.

Warning: The soldering point must remain at least 2.0mm away from the colloid bottom to prevent thermal damage to the epoxy.
📦 Package, Dimensions & Assembly Notes
The XL-234SYGC-L is designed for standard through-hole assembly (THT) and adheres to EIA standard packaging dimensions.
- Dimensions: The physical size is 3.0mm (diameter) x 2.0mm (thickness) with a lead length suitable for PCB insertion.
- Tolerance: General dimensional tolerances are ±0.50mm unless otherwise noted.
- Packaging: Supplied in anti-electrostatic foil bags, with 1000 pieces per bag.
- Moisture Sensitivity: Classified as MSL Level 2. The floor life at <30°C/60% RH is 1 year. Opening the bag requires adherence to moisture management protocols.
- Assembly: The long legs (Radial type) facilitate easy insertion into automated lead cutting equipment.
📈 Sourcing & Supply Considerations
When procuring the XL-234SYGC-L, consider the following supply chain factors to ensure production continuity:
- Binning Verification: Verify the specific bin codes (Voltage N12-8 to N13-1, Wavelength HYG03-06) with the supplier to match circuit design requirements.
- Authenticity Check: Confirm the packaging bears the XINGLIGHT branding and EIA standard labels to avoid counterfeit components.
- Sample Availability: Request engineering samples for validation of color temperature and intensity in the specific end-use environment.
- Lead Time: As a standard radial LED, this typically offers stable availability, but volume orders should be placed in advance to secure consistent binning.
❓ FAQ
Q: What is the forward voltage requirement for the XL-234SYGC-L? A: The typical forward voltage is 2.4V, with a maximum of 2.6V at 20mA. Ensure your drive circuit can supply a constant current within this range to maintain brightness consistency.
Q: Is this LED suitable for outdoor lighting applications? A: While the operating temperature range is -20°C to +85°C, the water-clear colloid is primarily designed for indoor indicators. For outdoor use, additional waterproofing measures must be considered due to the through-hole packaging.
Q: How should I handle the component regarding moisture sensitivity? A: The XL-234SYGC-L has a Moisture Sensitivity Level (MSL) of 2. If the moisture barrier bag has been open for more than 168 hours (1 year floor life), baking is required before reflow soldering to prevent popcorning.
Q: Can I drive this LED at higher currents for more brightness? A: The maximum continuous forward current is 20mA. While pulsed currents up to 80mA are allowed, exceeding 20mA continuously will shorten the lifespan and potentially cause thermal failure.
Q: What is the viewing angle of this LED? A: The typical viewing angle (2Ø1/2) is 110 degrees. This wide dispersion makes it ideal for indicator lights where the viewer may not be directly in front of the panel.
Q: Are there specific voltage and brightness binning options? A: Yes, XINGLIGHT provides specific binning codes (e.g., N12-8 for 2.0-2.2V, A1 for 50-100mcd). You should specify these bins when ordering to ensure uniformity across large production batches.
