5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω (matches calculated need: 470Ω)
• ✅ Tolerance: ±5% (meets or exceeds required ±5%)
• ✅ Power Rating: 0.5W (exceeds minimum required 0.33W; calculated dissipation is only 0.22W, so this is safe)
• ✅ Mounting Type: Surface Mount (1210 size, suitable for SMT assembly)
• ✅ Technology: Thick Film (matches required spec)
• ✅ RoHS Compliance: ROHS3 Compliant (environmentally compliant as required)

All selected part specs meet or exceed the requirements for safely and reliably limiting current to the LED in your application.
