What it does

The White LED 5mm is a super bright through-hole round LED diode designed for general-purpose illumination, indicator lights, DIY electronics projects, and embedded applications. Featuring a 5mm (T-1 3/4) package with a water-clear lens, it delivers cool white light with high luminous intensity and a focused viewing angle. With a typical forward voltage of 3.0V to 3.3V and 20mA forward current, it is ideal for use with Arduino, Raspberry Pi, breadboard circuits, and custom PCB designs. The LED utilizes advanced InGaN (Indium Gallium Nitride) chip technology for superior brightness, energy efficiency, and long operational life.

Key features

  • 5mm (T-1 3/4) round through-hole package
  • Super bright cool white light output
  • Water-clear lens for maximum light transmission
  • Low forward voltage: 3.0V – 3.3V typical
  • Standard 20mA forward current
  • High luminous intensity: 6,000 to 41,000 mcd
  • Focused viewing angle: 20° to 45°
  • Long lifespan: 50,000+ hours
  • Easy polarity identification: long leg = Anode (+), short leg = Cathode (–)
  • Compatible with Arduino, Raspberry Pi, and breadboard projects

Good to know

  • Always use a current-limiting resistor (typically 150Ω – 330Ω for 5V supply) in series with the LED to prevent damage from overcurrent.
  • Verify polarity before connecting — the longer leg is the Anode (+) and the shorter leg is the Cathode (–).
  • Do not exceed the maximum forward current of 20mA for continuous operation.
  • Avoid reverse voltage above 5V to prevent permanent LED damage.
  • Do not look directly at the LED when powered — high intensity can cause eye discomfort.
  • Store in a cool, dry place away from direct sunlight when not in use.
  • Specifications vary by manufacturer and model — verify datasheet before use.
