5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the calculated value for 22mA LED current (required: 470Ω ±5%).
• ✅ Tolerance: ±5% (required: ±5% or better).
• ✅ Power Rating: 0.333W (1/3W) – meets or exceeds the minimum requirement (≥0.33W). (Calculated dissipation: (12V-2V)^2/470Ω ≈ 0.21W, so 0.333W is suitable.)
• ✅ Mounting Type: Surface Mount (1206 package) – matches requirement.
• ✅ Technology: Thick Film – matches requirement.
• ✅ RoHS Compliance: ROHS3 Compliant.

All required specifications are satisfied. This resistor is suitable for safe, reliable LED current limiting in your 12V indicator circuit.
