Description / 0402 SMD Pure Green - Ultra Bright LED

The 0402 Pure Green SMD LED measures just 1.0 × 0.5mm (metric 1005) — the smallest surface-mount LED we carry. At this size, it disappears inside scale models and is barely visible on a PCB — but the output is strong enough to read as a clear indicator. Pure green (525nm) reads visibly brighter and more saturated than standard green — good for high-contrast status indicators.

At 1.0 × 0.5mm, these are at the limit of hand-soldering. Use flux paste, a fine-tip iron, and tweezers — or solder paste with reflow for volume work.

Common uses:

  • Scale modeling and dioramas — 1:72 military aircraft navigation lights, 1:35 armor vehicle headlights, Warhammer 40K cockpit instruments and eye lenses, Gundam mono-eye mods
  • Book nooks and shadow boxes — streetlights, window glow, and sign illumination at miniature scale (r/booknooks)
  • Consumer electronics repair — indicator LED replacement in iPhones, Galaxy phones, AirPods cases, laptop camera indicators, smartwatch status LEDs (r/microsoldering)
  • N scale and Z scale model railroad — DCC decoder lighting, locomotive headlights, structure interiors where 1.8mm is too large
  • Custom PCB design — DEF CON badges, SAO (Simple Add-On) boards, and compact hobby PCBs where board space is critical

DC power recommended: LEDs are designed for DC. Running on AC will cause flickering and reduce lifespan. If you're using a low-voltage AC source — such as a model railroad transformer output or DCC track voltage — convert it to DC first with a bridge rectifier.
