5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — matches the calculated value for 22mA with 12V supply and 2V LED forward voltage.
• ✅ Tolerance: ±5% — meets the requirement of ±5% or better.
• ✅ Power Rating: 1W — far exceeds the minimum 0.33W requirement, ensuring reliability and cool operation.
• ✅ Mounting Type: 2512 (Surface Mount) — fully suitable for SMT assembly.
• ✅ Technology: Thick Film — matches the specification.
• ✅ RoHS Compliance: ROHS3 Compliant — meets environmental requirements.

Conclusion: All required specifications are met or exceeded. This resistor is suitable and reliable for your LED current-limiting application.
