5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — Matches calculated value for 22mA at 12V - 2V drop across the LED.
• ✅ Tolerance: ±5% — Meets requirement (±5% or better).
• ✅ Power Rating: 0.5W — Exceeds minimum requirement of ≥0.33W.
  Power dissipated = (10V * 0.022A) = 0.22W. 0.5W rating offers robust safety margin.
• ✅ Mounting Type: 1206 Surface Mount — Suitable for PCB assembly as required.
• ✅ Technology: Thick Film — Acceptable (Thick Film or Thin Film specified).
• ✅ RoHS Compliance: ROHS3 Compliant — Meets environmental requirements.

Conclusion: All key specifications are met or exceeded. This resistor is a reliable and appropriate choice for the application.
