5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — Matches calculated value for 22mA through a 2V LED on 12V supply.
• ✅ Tolerance: ±1% — Tighter than required ±5%, offers even better accuracy.
• ✅ Power Rating: 0.4W — Exceeds minimum requirement of 0.33W. Calculated dissipation is P = I^2R = (0.022A)^2 × 470Ω ≈ 0.23W, so 0.4W provides adequate margin for reliability.
• ✅ Mounting Type: 0603 Surface Mount — Fully meets surface-mount requirement for PCB assembly.
• ✅ Technology: Thick Film — Matches specification (Thick Film or Thin Film).
• ✅ RoHS Compliance: Listed as ROHS3 Compliant.

Conclusion: All requirements are met or exceeded. This resistor is well suited for your LED current limiting application.
