📦 Package, Dimensions & Assembly Notes
- Package Type: 3mm Round LED equivalent (Diffused, Yellow Colloid).
- Dimensions: 6.2mm (W) x 6.2mm (H) x 14mm (L). All tolerances are $\pm 0.25mm$ unless noted.
- Moisture Sensitivity: MSL Level 2.
- Packaging: EIA Standard packaging in moisture-proof and anti-electrostatic foil bags.
- Assembly: Standard lead soldering profile applies. Ensure the soldering iron temperature does not exceed $260^{\circ}C$ for more than 6 seconds to prevent damage to the epoxy body.
🚀 Sourcing & Supply Considerations
- Binning Control: Verify specific grading codes (Brightness A4-A8, Voltage N12) during procurement to ensure uniformity in large batches.
- Storage: Use within 3 months of opening; otherwise, store in a dry cabinet ($<30^{\circ}C$, <70% RH) or nitrogen.
- Authenticity: Source from authorized channels to guarantee compliance with ROHS and EIA standards.
❓ FAQ
Q: What is the expected operating life of this LED?
A: Under standard operating conditions ($T_a=25^{\circ}C$, $I_F=20mA$), the XL-DZ504UYD is designed for a long operating life. Endurance testing shows 0 failures in 1000-hour working life tests and 1000-hour high-temperature/high-humidity tests (85°C/85-90% RH).
Q: Are there specific bins for voltage and brightness consistency?
A: Yes. XINGLIGHT provides tight binning options. Brightness is graded from A4 (300 mcd) to A8 (1200 mcd), and Forward Voltage is sorted into N12-7 (1.8-2.0V), N12-8 (2.0-2.2V), and N12-9 (2.2-2.4V) ranges to minimize variance in your BOM.
Q: What precautions are necessary for handling this component?
A: ⚠️ ESD Protection is mandatory. The component has an antistatic ability of 2000V, but surge voltage can damage it or reduce forward voltage. Use grounded equipment, anti-static wrist straps, and ion fans. Keep the electric field strength below 100V within 1 foot of the device.
Q: Can this LED withstand automated soldering processes?
A: Yes, it is designed for lead soldering. The maximum allowable soldering temperature is $260^{\circ}C$ for a maximum of 6 seconds. It has passed resistance to soldering heat tests at $250^{\circ}C$ twice without failure.
Q: What is the Moisture Sensitivity Level (MSL)?
A: The XL-DZ504UYD is classified as MSL Level 2. This means it can be exposed to a maximum factory floor life of 1 year at $30^{\circ}C$/85% RH before baking is required to prevent pop-corning during reflow.
