5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω (470 Ohms ±5%) matches the calculated value for limiting 22mA at 12V - 2V (LED VF).
• ✅ Tolerance: ±5% meets the requirement for current accuracy and brightness consistency.
• ✅ Power Rating: 0.333W (1/3W) equals the minimum required.
  Calculated power dissipation: P = I^2 * R = (0.022)^2 * 470 ≈ 0.227W (well below 0.333W).
• ✅ Mounting Type: 0805 chip is a standard surface-mount package, suitable for modern PCB assembly.
• ✅ Technology: Thick Film, as specified.
• ✅ RoHS Compliance: Marked as ROHS3 Compliant.

Conclusion: All required specifications are met.
This resistor is approved for use in your 12V red LED indicator application.
