5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the calculated requirement for 22mA LED current (470Ω = (12V-2V)/0.022A).
• ✅ Tolerance: ±5% meets the required ±5% or better.
• ✅ Power Rating: 0.333W (1/3W) meets or slightly exceeds the minimum required power rating (≥0.33W). Calculated dissipation is 0.22W (P = I²R = 0.022² × 470).
• ✅ Mounting Type: Surface Mount (1206 package) is suitable for SMD PCB assembly.
• ✅ Technology: Thick Film, as required.
• ✅ RoHS Compliance: ROHS3 Compliant (environmentally friendly).

Summary: All key specifications (resistance, tolerance, power, mounting, and compliance) are a good fit for your application.
