5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — Exactly matches the calculated requirement for a 12V-to-2V drop at 22mA (R = (12V-2V)/0.022A = 454.5Ω; 470Ω is the closest standard value and is correct).
• ✅ Tolerance: ±0.1% — Exceeds the requirement (±5% or better), offering even greater precision.
• ✅ Power Rating: 0.375W (3/8W) — Exceeds the minimum requirement (≥0.33W). Dissipated power is (10V × 0.022A = 0.22W), so 0.375W provides a good safety margin.
• ✅ Mounting Type: 0603 Surface Mount — Fully meets the "Surface Mount" requirement for automated assembly.
• ✅ Technology: Thin Film — Meets the requirement (Thick Film or Thin Film).
• ✅ RoHS Compliance: ROHS3 Compliant — Fully compliant for modern environmental standards.
• ✅ Other Features: Flame Proof, Moisture Resistant — Adds reliability in demanding environments.

Conclusion: All specifications meet or exceed the design requirements. This resistor is fully suitable for safely limiting current to a red LED in your 12V indicator application.
