Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the calculated requirement for 22mA current (R = (12V - 2V) / 22mA ≈ 455Ω; 470Ω is standard and safe).
• ✅ Tolerance: ±5% meets the requirement (±5% or better).
• ✅ Power Rating: 0.5W is above the minimum requirement of 0.33W. Power dissipated in the resistor is ~0.22W, so this rating offers good margin for reliability.
• ✅ Mounting Type: Surface Mount (1206 package) is as specified.
• ✅ Technology: Thick Film, which is acceptable.
• ✅ RoHS Compliance: ROHS3 Compliant.

All required specs are met or exceeded. This resistor is suitable for your LED current-limiting application.
