Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — matches calculated value for 22mA LED current ( (12V-2V)/22mA ≈ 455Ω; 470Ω is the nearest preferred value and is appropriate).
• ✅ Tolerance: ±5% — meets or exceeds the requirement of ±5% or better.
• ✅ Power Rating: 0.5W (1/2W) — exceeds the required ≥0.33W, providing extra safety margin.
  At 22mA, actual power dissipated = (10V × 0.022A) = 0.22W, so 0.5W is more than sufficient.
• ✅ Mounting Type: Surface Mount (1206 package) — matches requirement for SMT.
• ✅ Technology: Thick Film — meets specification.
• ✅ RoHS Compliance: Stated as ROHS3 Compliant — environmentally suitable.

All critical specs are met or exceeded. This part will work reliably as a current-limiting resistor for your 12V red LED circuit.
