- Two independently controlled colors for dual-color display
- Supports single-color, dual-color and color-mixing effects
- Uniform light output and good color consistency
- Good heat dissipation for continuous operation
- Supports automated placement and lead-free reflow soldering
Applications:
- Home appliance status indication
- Instruments and industrial control equipment
- Communications equipment, routers and control panels
- Automotive electronics and vehicle-mounted equipment
- Power supplies, chargers and smart home products
- LCD screens, buttons and backlight modules
- Consumer electronics and signal indication equipment
Product Features:
Chips: A high-quality dual-chip structure provides stable brightness in both colors and fast switching response.
Package: High-transmission encapsulation materials with good heat, moisture and aging resistance.
Lead frame: a highly reliable SMD lead frame provides good heat dissipation and stable solder joints.
Leads: Common-anode, common-cathode and independent-lead circuit configurations are available, with customization to customer requirements.
Packaging: Tape-and-reel packaging for high-speed placement machines and reflow soldering lines.

2835 Bi-Color SMD LED An 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: Can mid-power LEDs such as 2835/3014 be connected directly to 220V?
A: No. These LEDs are low-voltage 2-3.4V devices and require a constant-current driver supply. We can provide driver matching advice and support for complete luminaire solutions.
Q: What placement-machine accuracy does this LED require?
A: This product uses a 2835 package (2.8×3.5mm) with relatively large pads. Standard high-speed placement machines are adequate, with no special equipment accuracy requirements. For its multi-pad structure, stencil apertures must align individually with the pads. Supports lead-free reflow soldering (peak ≤260℃/≤3s).
