5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω – Correct value for 12V to 2V/22mA LED design.
• ✅ Tolerance: ±5% – Meets requirement.
• ✅ Power Rating: 0.333W (1/3W) – Meets the minimum requirement (≥0.33W).
      Calculated dissipation: (12V-2V) × 22mA = 220mW; 0.333W rating provides safe margin.
• ✅ Mounting Type: Surface Mount (0805) – Suitable for PCB assembly.
• ✅ Technology: Thick Film – Acceptable per spec.
• ✅ RoHS Compliance: Yes – RoHS3 Compliant.

Summary: All required specifications are satisfied. This resistor is well-suited for your LED indicator circuit, providing safe operation, reliability, and compliance with your design criteria.
