Circuit Examples

Basic LED Circuit with Current-Limiting Resistor

For a 5V supply with 30mA forward current:

  • Resistor value: (5V - 2.2V) / 30mA ≈ 93Ω (use 100Ω standard resistor)

For a 3.3V supply:

  • Resistor value: (3.3V - 2.2V) / 30mA ≈ 37Ω (use 39Ω or 47Ω standard resistor)

Technical Notes

  • Always use a current-limiting resistor in series with the LED to prevent damage
  • Observe polarity: longer lead is positive (anode), shorter lead is negative (cathode)
  • These are diffused LEDs, providing a wider viewing angle compared to clear LEDs
  • RoHS compliant components
  • Suitable for both manual assembly and automated pick-and-place
