5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω – matches calculated requirement for desired LED current.
• ✅ Tolerance: ±5% – meets or exceeds the ±5% requirement.
• ✅ Power Rating: 0.75W – well above the required ≥0.33W, ensuring excellent thermal headroom and long-term reliability.
• ✅ Mounting Type: Surface Mount (1206 size) – suitable for automated assembly and matches design intent.
• ✅ Technology: Thick Film – accepted for this application.
• ✅ RoHS Compliance: Yes (ROHS3 Compliant) – meets environmental requirements.

Result: All required specifications are met or exceeded. This resistor is ideal for safely and reliably limiting current to your red LED in a 12V indicator application.
