📦 Package, Dimensions & Assembly Notes
- Package Type: F5 (5mm Diameter) T-1 3/4 Through-Hole.
- Dimensions: 11.3mm (Total Length) x 15.0mm (Lead Span) x 10.3mm (Height).
- Tolerance: ±0.25mm unless specified.
- Material: Water-clear colloid (transparent epoxy).
- Assembly Warning: ⚠️ Ensure the soldering point is at least 2.0mm from the base of the colloid to prevent thermal damage to the epoxy and die. Wave soldering must not exceed 6 seconds at 240°C.
🏭 Sourcing & Supply Considerations
- Binning Availability: The part is available in specific brightness (A8-B4), voltage (N13), and color temperature (UW/CW) bins. Verify specific bin requirements before large-scale procurement to ensure light uniformity.
- MSL Classification: Moisture Sensitivity Level is 2 (MSL 2). Components must be soldered within 1 year of opening the moisture-proof bag; otherwise, baking is required.
- Authenticity: Source through XINGLIGHT authorized channels to guarantee adherence to RoHS standards and EIA-compliant packaging specifications.
❓ FAQ
Q: What forward voltage should I design my driver for?
A: Design your circuit to accommodate a maximum forward voltage (Vf) of 3.4V at 20mA to account for the upper binning limit and voltage drop over temperature, ensuring consistent current regulation.
Q: Is this LED suitable for outdoor street lighting applications?
A: While rated for urban lighting (亮化), the IP rating is not specified in this datasheet. For outdoor use where direct water exposure is possible, additional enclosure sealing (IP65+) is required to protect the leads and epoxy body.
Q: Can I reflow solder this component?
A: Yes, the datasheet specifies a reflow soldering maximum of 240°C for ≤6 seconds. However, as a through-hole component, wave soldering (240°C, ≤6s) or manual soldering (300°C, ≤3s) is the standard assembly method.
Q: What is the CIE color coordinate for this Cool White LED?
A: The typical CIE 1931 coordinates are x=0.278 and y=0.287, which places it in the Cool White region with a correlated color temperature of approximately 10000K.
