Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω ±5% — Matches calculated requirement for 22mA current limiting (470Ω = (12V - 2V) / 0.022A).
• ✅ Tolerance: ±5% — Meets or exceeds the ±5% specification, ensuring consistent LED brightness.
• ✅ Power Rating: 0.333W (1/3W) — Meets the minimum requirement (≥0.33W), supporting safe long-term operation.
  Actual power dissipation: (0.022A)² × 470Ω = 0.228W (well within the resistor's rating).
• ✅ Mounting Type: 0603 Surface Mount — Fully suitable for modern SMT PCB assembly.
• ✅ Technology: Thick Film — Acceptable for LED current limiting and specified in requirements.
• ✅ RoHS Compliance: ROHS3 Compliant — Environmentally friendly and globally accepted.

Conclusion: All specifications are matched or exceeded. This resistor is fully suitable for your 12V red LED indicator design.
