📦 Package, Dimensions & Assembly Notes
The XL-502SYGC utilizes the standard F5 radial package, widely compatible with most LED lead forming and insertion machinery.
- Dimensions: $5.5 \times 5.0 \times 8.7\text{mm}$ (L x W x H).
- Tolerance: $\pm 0.50\text{mm}$ unless otherwise noted.
- Lens: Water-clear colloid for high light transmission.
- Assembly: 🏗 Standard polarity orientation (Anode usually denoted by longer leg). Manual soldering requires strict temperature control ($300^\circ C$, <3s) to avoid lens cracking or degradation.
- Packaging: Supplied in moisture-proof and anti-electrostatic bags to maintain MSL 2 compliance.
📊 Sourcing & Supply Considerations
When sourcing the XL-502SYGC, consider the following supply chain and engineering factors:
- Brightness Binning: 📈 Codes A4–A6 indicate intensity bins (300–700mcd). For uniform panel lighting, procure from a single bin code.
- Voltage Binning: Codes N12-8 through N13-1 cover 2.0V–2.6V. Consistent $V_F$ bins are crucial for multi-LED series circuits or constant current driver design.
- Storage: MSL is Level 2. 🕒 Use components within 3 months of opening; otherwise, bake or store in a dry cabinet ($30^\circ C$, <70% RH).
- Authenticity: Verify packaging for EIA standard markings and anti-static foil to ensure genuine XINGLIGHT quality.
❓ Frequently Asked Questions
Q: What is the typical forward voltage drop for the XL-502SYGC?
A: The typical forward voltage ($V_F$) is 2.2V at a forward current of 20mA, with a maximum of 2.6V. Designers should account for the 2.0V–2.6V range across different batches to ensure current limiting resistors are adequately sized.
Q: Can this LED be used in outdoor environments?
A: While the operating temperature range (-20°C to +85°C) allows for various environments, the water-clear colloid is standard IP rated. For outdoor exposure (rain, UV), it is typically used inside enclosures or protected fixtures, such as urban lighting signs that have weatherproof housing.
Q: What is the difference between Dominant Wavelength and Peak Wavelength?
A: Dominant Wavelength ($\lambda_d$) is the color perceived by the human eye (565–575nm for this model), while Peak Wavelength ($\lambda_p$) is the physical maximum output of the spectrum (570nm). Engineers should focus on Dominant Wavelength for color matching.
Q: How should I handle the component regarding moisture sensitivity?
A: The XL-502SYGC is rated at Moisture Sensitivity Level (MSL) 2. This means it can be exposed to factory ambient conditions for up to one year before baking is required. After opening the moisture-proof bag, floor life should be limited to prevent absorption during soldering.
Q: What is the viewing angle of this LED?
A: The typical viewing angle ($2\theta_{1/2}$) is 30 degrees. This makes it suitable for focused indicators rather than wide-area diffuse backlighting.
Q: Are there specific bin codes for voltage selection?
A: Yes, XINGLIGHT sorts these LEDs into voltage bins N12-8 (2.0–2.2V), N12-9 (2.2–2.4V), and N13-1 (2.4–2.6V). Selecting a specific bin is recommended for designs requiring tight voltage regulation.
