5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω ±5% — Matches calculated requirement for desired current through the LED.
• ✅ Tolerance: ±5% — Meets or exceeds the specified tolerance requirement.
• ✅ Power Rating: 0.333W (1/3W) — Exactly meets the minimum required power rating for safe long-term operation.
  Power dissipated in resistor: (12V - 2V)² / 470Ω ≈ 0.213W, so 0.333W is sufficient.
• ✅ Mounting Type: Surface Mount (0805) — Suitable for SMT assembly as required.
• ✅ Technology: Thick Film — Acceptable for this application.
• ✅ RoHS Compliance: ROHS3 Compliant — Meets environmental requirements.

All required specifications are met. This resistor is a suitable and reliable choice for your 12V red LED current limiting application.
