0402 SMD LED – Miniature Surface Mount Chip LED
Product Description
The0402 SMD LED is an ultra-compact surface-mount light-emitting diode with a footprint of just 1.0mm x 0.5mm. Designed for high-density PCB layouts, this 0402 SMD LED is the industry-standard choice for space-constrained applications in mobile devices, wearables, and portable electronics. Fully compatible with automated SMT assembly, the 0402 SMD LED provides bright, reliable illumination in the smallest possible package.
Key Features
- Ultra-Small Size: At 1.0mm x 0.5mm, the 0402 SMD LED saves valuable board space compared to larger 0603 or 0805 components.
- Low Power Operation: Ideal for battery-powered devices, the 0402 SMD LED operates efficiently at low forward currents.
- Wide Color Selection: Available in Red, Green, Blue, Yellow, Yellow-Green, White.
- SMT Compatible: Supplied in tape-and-reel packaging for high-speed pick-and-place assembly.
- RoHS Compliant: Meets environmental standards for lead-free manufacturing.
Applications
The0402 SMD LED is widely used for status indication and backlighting in:
- Smartphones, tablets, and TWS earbuds
- Smartwatches and fitness trackers
- Laptops, routers, and USB peripherals
- Automotive dashboard indicators
- Medical handheld devices and industrial controls
