Select a Resistor to Drive an LED

• ✅ Resistance: 470 Ω – Matches calculated requirement for 22mA LED current.
• ✅ Tolerance: ±1% – Better than required (±5% or better).
• ✅ Power Rating: 0.5W (1/2W) – Exceeds minimum requirement of 0.33W. Power dissipated in application is (12V-2V) × 22mA = 220mW, so this part is well within safe limits.
• ✅ Mounting Type: Surface Mount (1206 package) – Suitable for SMT assembly.
• ✅ Technology: Thick Film – Matches requirement.
• ✅ RoHS Compliance: ROHS3 Compliant – Meets environmental requirement.

Result: All key specifications are met or exceeded. This resistor is well-suited for safely and reliably limiting current to your red LED in a 12V application.
