XL-304SYGC LED: 570nm Yellow-Green for High-Density PCBs

📌 Product Overview

The XL-304SYGC is a 3.8mm through-hole LED emitting a stable yellow-green light (570nm peak wavelength), optimized for high-reliability applications. Its compact F3 package and low forward voltage (1.8–2.6V @ 20mA) make it ideal for space-constrained designs. Engineered for durability, it supports a wide operating temperature range (-40°C to +85°C) and meets ROHS standards, ensuring compliance in global supply chains.


🔧 Typical Applications

  • Automotive Electronics: Dashboard indicators, control panels
  • Industrial Controls: Status LEDs, machinery interfaces
  • Consumer Electronics: Toys, digital clocks, home appliances
  • Medical & Educational Devices: Instrumentation, teaching tools
  • Urban Lighting: Decorative, low-power signage

📦 Package, Dimensions & Assembly Notes

  • Package Type: F3 through-hole (3.8mm diameter) with white epoxy colloid.
  • Dimensions: 3.8×3.0×5.2×28mm (±0.5mm tolerance).
  • Assembly: Manual soldering at 300°C (3s); keep lead bend ≥2.0mm from the base to avoid stress.
  • Packaging: Moisture-proof, anti-static foil bags (EIA standard).

🚀 Sourcing & Supply Considerations

  • Binning Options: Available in brightness (A1–A3), voltage (N12–N13), and wavelength (HYG02–HYG06) grades.
  • Reliability: Tested for 1,000hrs under high-temp/humidity (85°C/85% RH) and thermal cycling.
  • Supply: RoHS-compliant; verify authenticity through authorized distributors to counter counterfeits.

❓ FAQ

Q: What is the brightness tolerance for the XL-304SYGC?
A: Luminous intensity has a ±10% deviation (e.g., 300mcd ±30mcd).

Q: Is this LED suitable for reflow soldering?
A: Yes, but only for wave/reflow at 240°C for ≤6s; manual soldering must be ≤300°C for 3s.

Q: Can it operate in automotive environments?
A: Its -20°C to +85°C range suits most automotive applications, but verify AEC-Q102 if required.

Q: How are units packaged for mass production?
A: Units are packed in moisture-proof, anti-static bags to prevent ESD damage during storage.

Q: What’s the typical lead time for bulk orders?
A: Lead times vary by region; confirm with XINGLIGHT’s authorized distributors for current stock.
