Select a Resistor to Drive an LED

RC1206JR-7W470RL

470 Ohms ±5% 0.5W, 1/2W Chip Resistor 1206 (3216 Metric) Moisture Resistant Thick Film

✅ Resistance: 470Ω matches required value for 22mA LED current from 12V (calculated: (12V-2V)/22mA ≈ 455Ω; 470Ω is the standard closest value, ensuring safe current).
✅ Power Rating: 0.5W > 0.33W minimum required. Power dissipated = (22mA)^2 × 470Ω ≈ 0.23W, so 0.5W is more than sufficient for safe, reliable operation.
✅ Tolerance: ±5% matches requirement (±5% or better).
✅ Mounting: 1206 package is surface-mount, as specified.
✅ Technology: Thick Film—acceptable per requirements.
✅ RoHS Compliance: Marked as ROHS3 Compliant.

Conclusion: All specs meet or exceed requirements. This resistor is approved for use as a current limiter in your LED circuit.
