5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the calculated value for 22mA LED current [(12V-2V)/22mA ≈ 455Ω, next standard value 470Ω is correct].
• ✅ Tolerance: 1% (better than required ±5%).
• ✅ Power Rating: 0.5W (greater than the required ≥0.33W). Power dissipated in use is P = I²R ≈ 0.022²×470 ≈ 0.23W, so 0.5W is safe and reliable.
• ✅ Mounting Type: 1210 Surface Mount (meets requirement).
• ✅ Technology: Thick Film (matches requirement).
• ✅ RoHS Compliance: Specified as ROHS3 Compliant.

Conclusion: All required specifications are met or exceeded by the selected YAGEO RC1210FR-07470RL resistor. This is a suitable and reliable choice for your LED current limiting application.
