📌 Product Overview
The XL-302SYGD is a standard F3 (3mm) radial LED from XINGLIGHT, featuring a green colloid and a dominant wavelength of 570nm. It is engineered primarily for through-hole PCB assembly (THT) in status indication and backlighting scenarios. 💡
💡 Design Focus: This component balances luminous intensity (up to 300mcd) with low power consumption (70mW max). It is suitable for general indication in consumer appliances, automotive interiors, and industrial control panels.
🔌 Typical Applications
Based on its robust operating temperature range (-20°C to +85°C) and moisture sensitivity level, the XL-302SYGD is optimized for the following use cases:
- Consumer Electronics: Status indicators for home appliances and digital devices.
- Automotive Electronics: Dashboard illumination and interior signaling (non-critical).
- Industrial Instrumentation: Indicator lights for power supplies and communication equipment.
- Urban Lighting & Decorations: Accent lighting in architectural or signage applications.
- Educational & Medical Toys: Low-voltage indicators requiring safe DC drive.

❓ FAQ
Q: What is the difference between the A1, A2, and A3 brightness codes?
A: These codes refer to the Luminous Intensity (Iv) binning. A1 ranges from 50-100 mcd, A2 from 100-200 mcd, and A3 from 200-300 mcd at 20mA. Selecting the correct bin ensures visual consistency across your product's LED array.
Q: Can this LED be used in outdoor applications?
A: While the operating temperature supports a wide range, the IP rating of the final product depends on the enclosure design. The component itself is not waterproof; it requires a protective housing for outdoor or high-humidity environments.
Q: What are the storage requirements to prevent damage?
A: The XL-302SYGD has an MSL of 2. If the moisture-proof bag is opened, the components should be soldered within 1 year (floor life). For storage exceeding this, baking may be required to prevent popcorning during soldering.
Q: Is the forward voltage drop critical for my battery design?
A: Yes. The VF ranges from 1.8V to 2.6V. If driving multiple LEDs in series or from a low-voltage source (e.g., 3V battery), you must select the specific voltage bin (e.g., N12-7 for 1.8-2.0V) to ensure current regulation and brightness stability.
Q: How close can the solder joint be to the LED body?
A: The datasheet specifies a minimum distance of 2.0mm from the bottom of the colloid to the soldering point. Closer soldering risks thermal damage to the epoxy and internal bond wires.
