5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — matches calculated requirement for 22mA current with a 12V supply and 2V LED forward voltage.
• ✅ Tolerance: ±5% — meets the required tolerance (±5% or better).
• ✅ Power Rating: 0.5W — exceeds the minimum required rating of 0.33W, ensuring safe operation and long-term reliability.
• ✅ Mounting Type: Surface Mount (1206 package) — matches the specified mounting requirement.
• ✅ Technology: Thick Film — meets the requirement for Thick Film or Thin Film.
• ✅ RoHS Compliance: RoHS3 Compliant — satisfies lead-free and environmental safety requirement.

Conclusion: All specifications match or exceed the requirements. The selected resistor (TE Connectivity CRGH1206J470R) is a suitable and reliable choice for the application.
