5. Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the calculated requirement for setting ~22mA through the LED.
• ✅ Tolerance: ±5% meets the requirement (±5% or better).
• ✅ Power Rating: 0.4W > 0.33W required, providing a safe margin. (Actual dissipation: (0.022A)² × 470Ω ≈ 0.227W)
• ✅ Mounting: MELF 0204 is a standard surface mount format, as required.
• ✅ Technology: Thin Film (acceptable: Thick or Thin Film).
• ✅ RoHS Compliance: ROHS3 Compliant per datasheet and DigiKey listing.

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