3528 Addressable SMD LEDs A 5V addressable SMD LED with an integrated driver IC (compatible with WS2812/SK6812 single-wire serial protocols). Each LED supports individually programmable full-color addressing and cascade control, for light strips, ambient lights and pixel matrices. Supplied directly by Dongguan Hongcheng Optoelectronics Co., Ltd. (an international member of Guangyu Group, with over 20 years of LED packaging experience). Uses A-grade chips and 99.99% pure gold wire bonding, with RoHS certification. Free samples and custom IC protocols, pin configurations and refresh rates are available. Download the datasheet PDF on this page for complete electrical specifications and mounting dimensions.
Q: What are the chromaticity BIN ranges for addressable LEDs?
A: The full-color series is shipped with brightness and color binning based on CIE chromaticity coordinates. Color difference within the same batch is Δu'v'≤0.003. Custom BIN ranges are available to meet customer color-gamut requirements.
Q: What placement-machine accuracy does this LED require?
A: This product uses a 3528 package (3.5×2.8mm) with relatively large pads. Standard high-speed placement machines are adequate, with no special equipment accuracy requirements. For its integrated-IC multi-pad structure, stencil apertures must align individually with the pads. Visual inspection or AOI after placement is recommended to verify solder joint quality. Supports lead-free reflow soldering (peak ≤260℃/≤3s).
