5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — meets the calculated requirement for 22mA through a 2V LED from 12V ((12V-2V)/22mA ≈ 455Ω; next standard value 470Ω is correct).
• ✅ Tolerance: 1% — tighter than required (±5% or better). This ensures consistent, reliable LED brightness.
• ✅ Power Rating: 1W — much higher than the required 0.33W. This provides excellent safety margin for thermal reliability.
      Power dissipated: (22mA)² × 470Ω ≈ 0.228W.
• ✅ Mounting Type: Surface Mount, 2512 package — matches requirement.
• ✅ Technology: Thick Film — acceptable per requirements.
• ✅ RoHS Compliance: Yes (ROHS3 Compliant & REACH Unaffected).

Summary: All specifications meet or exceed the design requirements. The resistor is well-suited for safe, reliable LED current limiting in your 12V indicator circuit.
