6028 RGB 4-Pin Common-Cathode SMD LEDs An indicator LED in a 6028 SMD package, with a forward voltage of 1.8~3.4V (depending on emission color) and a 20mA-class drive current. Supports fully automated placement and reflow soldering. Supplied directly by Dongguan Hongcheng Optoelectronics Co., Ltd. (an international member of Guangyu Group with over 20 years of LED packaging experience), it features 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 specifications and mounting dimensions.
Q: Does this datasheet provide an integrated-IC or single-wire cascade control protocol?
A: The HC-B3-60628A02-RGBA6 datasheet specifies an RGB four-pin common-cathode structure, without WS2812 compatibility or a single-wire cascading control protocol. The “RGB full-color” name alone does not establish that it has a built-in IC. Follow this model's datasheet and engineering confirmation for selection and wiring.
Q: What placement-machine accuracy does this LED require?
A: This product uses a 6028 package (6.0×2.8mm) with relatively large pads. Ordinary high-speed placement machines meet its needs, with no special equipment accuracy requirements. Its multiple-pad structure requires each stencil aperture to align with its corresponding pad. Supports lead-free reflow soldering (peak ≤260℃/≤3s).
