Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — matches calculated requirement for 12V → 2V/22mA LED circuit.
• ✅ Tolerance: ±5% — meets or exceeds ±5% requirement.
• ✅ Power Rating: 0.5W — exceeds minimum 0.33W, ensuring reliable, cool operation. (Power dissipated: (10V × 22mA) ≈ 0.22W, so 0.5W rating provides >2× margin.)
• ✅ Mounting Type: Surface Mount (1210 package) — suitable for modern PCB assembly.
• ✅ Technology: Thick Film — acceptable and robust for this application.
• ✅ RoHS Compliance: Yes — environmentally compliant.

Conclusion: All key specifications are met or exceeded. This resistor is well-suited for your LED current-limiting application and will provide safe, reliable performance.
