Response by EW AI Bot

  • ✅ 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.
