4509RGBW SMD LEDs An LED in a 4509 package, designed as a SMD indicator LED with a forward voltage of 1.8~3.4V (depending on emission color) and a drive current in the 20mA range. Supports fully automatic SMT assembly and reflow soldering. Factory-direct from Dongguan Hongcheng Optoelectronics Co., Ltd. (an international member of Guangyu Group with over 20 years of LED packaging experience), it uses Grade A chips and 99.99% pure gold wire bonding and is RoHS certified. Free samples and custom brightness binning, color-temperature binning and tape packaging are available. Download the datasheet PDF on this page for complete electrical parameters 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 4509 package (4.5×0.9mm) has relatively large pads. A standard high-speed placement machine is sufficient, with no special accuracy requirements. Its multiple-pad structure requires each stencil aperture to align with the corresponding pad. Lead-free reflow soldering is supported (peak ≤260℃/≤3s).
