5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the calculated value for 22mA through a 2V red LED on 12V supply.
• ✅ Tolerance: ±5% meets the requirement (±5% or better).
• ✅ Power Rating: 0.5W (1/2W) exceeds the minimum requirement of 0.33W. This provides a good safety margin for long-term reliability.
• ✅ Mounting Type: Surface Mount (1206 package) is suitable for your design.
• ✅ Technology: Thick Film, as required.
• ✅ RoHS Compliance: ROHS3 Compliant.

Conclusion: All specifications are satisfied. The selected resistor is approved for your LED current limiting application.
