XL-302SYGC 3mm LED: Bin Selection & Forward Voltage Analysis

The XL-302SYGC is a standard 3mm Yellow Green Through-Hole LED designed for status indication and panel illumination.

XL-302SYGC 3mm LED: Bin Selection & Forward Voltage Analysis

📌 Product Overview

The XINGLIGHT XL-302SYGC is a 3mm diffused Through-Hole Technology (THT) LED designed for reliable indication in general-purpose circuitry. Housed in a white water-clear colloid, this device emits a standard Yellow Green light with a dominant wavelength of 570nm, making it ideal for dashboard lighting and signal status.

💡 This component is optimized for designs requiring low power consumption and straightforward assembly on PCBs or flexible wiring. It is fully ROHS compliant and supports standard DC drive logic.

🚀 Typical Applications

Based on its 30-degree viewing angle and moderate luminous intensity, the XL-302SYGC is best suited for indication rather than illumination.

  • Consumer Electronics: Status indicators for home appliances and digital devices.
  • Automotive: Dashboard signal lights and interior cabin indicators (non-critical).
  • Industrial: Control panel status lights and communication equipment feedback.
  • Education & Toys: Electronic teaching aids and electronic toy indicators.
  • Urban Infrastructure: Traffic instruction signage and city lighting accents.

📊 Key Technical Specifications

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

💡 Design Note: The wide range in luminous intensity (50-300mcd) requires specific binning selection if visual uniformity is critical for the end product.

🔒 Absolute Maximum Ratings & Process Limits

Exceeding these ratings may cause permanent device failure. Design margins must account for these limits to ensure long-term reliability.

⚠️ Critical Warning: Ensure the soldering point maintains a distance of at least 2.0mm from the bottom of the colloid to prevent thermal damage to the epoxy package.

📏 Package, Dimensions & Assembly Notes

The XL-302SYGC utilizes a standard F3 radial package with short leads, suitable for compact PCB layouts or manual wiring.

  • Dimensions: The outer diameter is 3.0mm with a total length of 18mm.
  • Tolerance: General dimensional tolerances are ±0.50mm unless otherwise noted.
  • MSL Level: The component is classified at Moisture Sensitivity Level 2 (MSL 2).
  • Assembly: It is packed in moisture-proof, anti-static foil bags to prevent damage prior to assembly.
  • Mounting: Designed for wave soldering or manual insertion processes.

📈 Sourcing & Supply Considerations

When integrating the XL-302SYGC into BOMs, procurement teams should prioritize supply chain verification to avoid counterfeit risks common in standard LED commodities.

  • Binning Codes: Verify specific Brightness (A1-A3), Voltage (N12-7 to N13-1), and Wavelength (HYG02-HYG06) codes to match design requirements.
  • Authenticity: Source exclusively through authorized XINGLIGHT channels to guarantee ROHS compliance and optical consistency.
  • Sample Support: Request pre-production samples to verify color binning and intensity matching for dashboard clusters.

❓ FAQ

Q: What is the typical forward voltage drop for this LED?
A: The typical forward voltage (VF) is 2.2V at a forward current of 20mA. However, this can range from 1.8V to 2.6V depending on the specific binning grade.

Q: Can this LED be used for outdoor street lighting?
A: While listed under "Urban lighting," this 3mm THT component is designed for indicator lights or decorative accents rather than high-power street illumination due to its maximum 300mcd intensity.

Q: What are the storage requirements to prevent moisture damage?
A: The XL-302SYGC has an MSL of 2. It should be stored in a dry environment within -40°C to +85°C. The packaging uses anti-static foil bags to provide necessary moisture barrier protection.

Q: How close can the solder joint be to the LED body?
A: The datasheet mandates that the welding point must be at least 2.0mm away from the bottom of the colloid to prevent heat damage during soldering operations.

Q: Is this component suitable for automotive dashboards?
A: Yes, it is suitable for interior dashboard indicators. However, for exterior lighting or critical safety signals, engineers must verify specific automotive grade compliance and temperature derating.
