10-Pack 0402 SMD Prewired LEDs (5-16V Operation)

Ultra-miniature 0402 SMD LEDs (1.0mm x 0.5mm) with built-in resistor for 5-16V operation.

0402 prewired LED 12V assemblies designed for precision lighting in model railways, control panels, scale models and compact DIY electronics projects.

These 0402 prewired LEDs are ready-to-install ultra-micro SMD LEDs for 12V systems (5–16V range), with a built-in resistor for simple, reliable wiring.

Ideal for applications where space is extremely limited and discreet lighting is essential.

Key Features

• 0402 SMD prewired LEDs – extremely small and easy to conceal
• 12V operation (5–16V range)
• Built-in resistor – no extra components required
• Assorted colours (colors) for flexible use (white, warm white, Red, Green, Blue, Yellow, Orange, Pink or Purple)
• Fine pre-soldered wires for delicate installations
• Ready to install – just connect and power

No soldering required — just connect directly to your 12V supply.

Applications

• Model railway lighting and signal indicators
• Scale models and dioramas
• Control panels and micro indicators
• Arduino and DIY electronics projects
• Model railway, automotive and 12V hobby applications

SMD 0402 LED Dimensions

SMD LEDs (Surface Mount Device) LEDs are among the most miniature LEDs available and are produced in several standardized sizes.

• Model: 0402 (1005 Metric) measures 1.0mm (L) x 0.5mm (W)
• Model: 0603 (1608 Metric) measures 1.6mm (L) x 0.8mm (W)
• Model: 0805 (2012 Metric) measures 2.0mm (L) x 1.25mm (W)
• Model: 1206 (3216 Metric) measures 3.2mm (L) x 1.6mm (W)

Specifications

These LEDs are widely used in electronics projects for model railway lighting, vehicle indicators, dioramas, and other miniature lighting applications where extremely small size and minimal visibility are critical.

Compared to incandescent bulbs, SMD LEDs run cooler, last longer, and are available in a wide variety of colours (colors).

The SMD LEDs are some of the smallest light sources available and can be very difficult to solder wires to without specialized tools and experience.

We offer these prewired SMD LEDs with a pair of 11-inch (28cm) connection wires already attached along with a built-in dropping resistor allowing for safe connection to supply voltages of 5V to 16V. If you are experienced and have the necessary fine soldering equipment, we also offer the same LEDs in DIY bulk options along with versions without resistors (see our SMD LED options) to help reduce costs when wiring your own LEDs.

Power Requirements

These LEDs already have a series resistor installed, which allows them to operate over a wide voltage range without needing a separate resistor. These LEDs are conservatively rated for operation from 5V to 16V and require no additional series resistor.
