- Ensure ROHS compliance and MSL-2 handling for manufacturing reliability.
- Request samples for validation before mass production to mitigate cross-referencing risks.
❓ FAQ
Q: What are the brightness binning options for this LED?
A: Red LEDs are graded A5 (400-500 mcd) to A6 (500-700 mcd); blue LEDs range from A9 (1200-1500 mcd) to B2 (1800-2100 mcd).
Q: Is this LED suitable for automotive applications?
A: Yes, it meets automotive interior requirements with a -20°C to +85°C operating range and long-term reliability testing.
Q: What soldering precautions should be followed?
A: Reflow at 240°C (≤6s) or manual solder at 300°C (3s). Maintain a 2.0mm distance from the colloid base to prevent damage.
Q: How does ROHS compliance affect production?
A: As a ROHS-compliant component, it avoids hazardous materials, simplifying regulatory compliance for global markets.
Q: Can this LED replace single-color alternatives in existing designs?
A: Yes, its dual-color capability and compact footprint offer a drop-in solution for applications needing red/blue indication.
