Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — Matches calculated requirement for setting ~22mA LED current:
  R = (12V - 2V) / 0.022A ≈ 454.5Ω (standard value 470Ω is ideal).
• ✅ Tolerance: ±5% — Meets or exceeds the required ±5% tolerance.
• ✅ Power Rating: 0.333W (1/3W) — Meets the minimum requirement (≥0.33W).
  Calculated dissipation: P = I^2 × R = (0.022A)^2 × 470Ω ≈ 0.227W — Safe margin.
• ✅ Mounting Type: Surface Mount (0603 package) — Fully compliant with requirement.
• ✅ Technology: Thick Film — Acceptable for LED current limiting, as specified.
• ✅ RoHS Compliance: ROHS3 Compliant — Fully compliant.

Conclusion: All key specifications are met or exceeded.
ERJ-PA3J471V is fully suitable for safely and reliably limiting current to your red LED in this 12V indicator circuit.
