5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the required value for 22mA with a 12V supply and 2V LED drop.
• ✅ Tolerance: ±5%, meets the requirement (±5% or better).
• ✅ Power Rating: 0.333W (1/3W) meets the minimum requirement (≥0.33W). Calculated dissipation is (10V x 22mA) = 0.22W, so there's adequate margin for reliability.
• ✅ Mounting Type: 1206 (Surface Mount), as required.
• ✅ Technology: Thick Film, matches the specification.
• ✅ RoHS Compliance: ROHS3 Compliant.

Conclusion: All key specifications match the requirements for safe, reliable LED current limiting in this application. This resistor is approved for use.
