5. Select a Resistor to Drive an LED

• ✅ Resistance Value: 470Ω matches the calculated need for 12V → 2V @ 22mA ([10V / 0.022A] ≈ 455Ω, nearest E24 is 470Ω).
• ✅ Tolerance: ±5% meets or exceeds the ±5% requirement.
• ✅ Power Rating: 0.333W (1/3W) exactly meets the ≥0.33W minimum. Power dissipated = (0.022A)^2 × 470Ω ≈ 0.227W, so this is suitable with margin.
• ✅ Mounting Type: 0805 Surface Mount package is correct for SMT assembly.
• ✅ Technology: Thick Film is accepted per requirements.
• ✅ RoHS Compliance: ROHS3 Compliant, so suitable for modern manufacturing and environmental standards.

No issues detected. This resistor (TE Connectivity CRGH0805J470R) is well-suited for your 12V red LED current-limiting application and will ensure safe, reliable operation.
