9V 1W White SMD LED-2835

9V 1W White SMD LED (2835 Package) is a powerful, highly efficient light source engineered for modern illumination designs that require excellent brightness from a compact footprint. This particular SMD 2835 LED operates at a nominal 9V, a configuration that allows designers to utilize fewer parallel strings and more series connections in their lighting arrays, consequently simplifying driver circuitry and improving system reliability. The high 1W power rating, coupled with the industry-standard 2.8 mm x 3.5 mm package size, enables manufacturers to achieve impressive lumen output and energy savings in various products. Furthermore, its small size and superior thermal performance make it an ideal choice for high-density, cost-effective LED lighting solutions.

Key Features:

• High Voltage Operation: The nominal 9V forward voltage (V_F) is perfect for designing LED strips and panels with high series counts, reducing current requirements and heat generation.
• High Luminous Efficacy: This 1W LED delivers excellent lumen output per watt (≥ 130 lm/W typical), therefore achieving superior energy efficiency compared to older LED technologies.
• Industry Standard Footprint: The 2835 package size (2.8 mm x 3.5 mm) ensures direct compatibility with existing manufacturing processes and standard PCB layouts.
• Thermal Performance: The package design provides low thermal resistance, enabling high-power operation (1W) while maintaining a reliable junction temperature (T_j).
• Wide Viewing Angle: A typical 120° viewing angle ensures uniform light distribution, crucial for general lighting and panel backlighting.

Technical Specifications:

• Package Type: SMD 2835 (2.8 mm x 3.5 mm)
• Typical Power Dissipation: 1 W
• Nominal Forward Voltage (V_F): 9.0 V (±0.3 V tolerance typical)
• DC Forward Current (I_F): 100 mA (Max 120 mA recommended)
• Typical Luminous Flux: 120 to 140 lm (Bin dependent)
• Color Temperature (CCT): 6000 K to 6500 K (Cool White, or Natural White depending on bin)
• Viewing Angle: 120°

Mechanical Specifications:

• Dimensions (L x W x H): 2.8 mm x 3.5 mm x ≈ 0.65 mm
• Mounting: Surface Mount Technology (SMT) Reflow Soldering
• Solder Pad Configuration: Large cathode pad and smaller anode pad for high thermal conductivity.
• Material: Epoxy encapsulation with high-reliability inner components.

Dimensions:

• LED Body Length: 3.5 mm (±0.1 mm)
• LED Body Width: 2.8 mm (±0.1 mm)
• Thickness/Height: ≈ 0.65 mm
• Pad-to-Pad Spacing: Varies by manufacturer, however, the standard 2835 configuration is maintained.

Pinout and Wiring:

• Anode (+): The smaller solder pad on the package side, typically marked with a small notch or triangle. Connect the positive terminal of the 9V power supply to this pin.
• Cathode (−): The larger solder pad, often covering most of the underside of the LED package, providing the main thermal path. Connect this pin to the circuit ground (GND).
• Wiring Note: Always operate the LED with a constant current source or a current-limiting resistor to maintain the 100 mA nominal current, since exceeding the maximum I_F shortens the component’s lifespan dramatically.
