5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω ±5%
  Correct value for 22mA LED current (12V supply, 2V LED forward voltage).
• ✅ Tolerance: ±5%
  Meets the requirement of ±5% or better.
• ✅ Power Rating: 0.75W (3/4W)
  Exceeds the minimum required 0.33W, providing a robust safety margin for long-term reliability.
  (Actual power dissipated will be P = (12V-2V)^2 / 470Ω = ~0.21W)
• ✅ Mounting Type: Surface Mount (2010 package)
  Suitable for modern PCB assembly.
• ✅ Technology: Thick Film
  Meets design preference for either Thick or Thin Film.
• ✅ RoHS Compliance: ROHS3 Compliant
  Environmentally friendly and suitable for global markets.

All specified criteria are satisfied. This resistor is highly suitable for your LED current-limiting application.
