Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω — matches calculated value for 22mA LED current at 12V supply.
• ✅ Tolerance: 1% — better than the required ±5%, providing tighter control over current.
• ✅ Power Rating: 2W — greatly exceeds minimum requirement of 0.33W, ensuring safe operation with ample margin (actual dissipation ≈0.22W).
• ✅ Mounting Type: Surface Mount (2512 package) — meets requirement for SMD assembly.
• ✅ Technology: Thick Film — matches requirement (thick or thin film allowed).
• ✅ RoHS Compliance: ROHS3 Compliant — meets environmental requirements.

Result: All requirements are met or exceeded. This resistor is well-suited for the application.
