XL-304UWC LED: High-Brightness White Component for Consumer & Industrial Applications

📌 Product Overview

The XL-304UWC is a through-hole white LED with a F3/3.8x3.0x5.2x28mm package, offering high luminous intensity (up to 10,000 mcd) and a 10,000K color temperature. Designed for reliability, it operates from -20°C to +85°C and meets ROHS standards. Its low forward voltage (2.8–3.4V) and fast startup make it ideal for compact, energy-efficient designs in consumer and industrial applications.


🔍 Typical Applications

  • Home appliances & digital devices
  • Automotive electronics
  • Lighting decoration & urban lighting
  • Medical beauty instruments
  • Electronic toys & teaching equipment

📦 Package, Dimensions & Assembly Notes

The XL-304UWC features a moisture-proof, anti-static foil bag package. Key dimensions: 3.8x3.0x5.2mm (body) with 28mm leads. Soldering requires manual welding at 300°C (3s) or reflow at 240°C (≤6s), with a 2.0mm minimum distance from the lead to the epoxy body.


🚀 Sourcing & Supply Considerations

  • Grading options available for luminosity (B9/C1) and voltage (N13-3/4/5).
  • RoHS-compliant with MSL-2 moisture sensitivity.
  • Recommended storage: ≤30°C, ≤70% RH, in original packaging for ≤3 months.

❓ FAQ

Q: What is the luminosity grading for XL-304UWC?
A: Two bins: B9 (6,000–8,000 mcd) and C1 (8,000–10,000 mcd) at IF=20mA.

Q: What are the soldering conditions?
A: Reflow at 240°C (≤6s) or manual solder at 300°C (3s). Keep lead-to-body distance ≥2.0mm.

Q: Is this LED suitable for automotive use?
A: Yes, but high-reliability applications (e.g., traffic control) require additional validation per datasheet.

Q: How should LEDs be stored long-term?
A: Store at ≤30°C, ≤70% RH. For >3 months, use a desiccant or nitrogen-filled container.

Q: What is the reverse current rating?
A: ≤10 μA at VR=5V.

Q: Does the LED comply with RoHS?
A: Yes, it is an RoHS-compliant environmental product.
