  • ✅ Resistance (470Ω): Selected resistor is 470 Ohms, matching the calculated value for setting ~22mA through the LED.
  • ✅ Tolerance (±5%): Meets the requirement for ±5% or better.
  • ✅ Power Rating (≥0.33W): The resistor is rated for 0.5W (1/2W), which exceeds the minimum required 0.33W.
    Calculation Check: Power dissipated = (V_supply - V_F)^2 / R = (10V)^2 / 470Ω ≈ 0.213W. The 0.5W rating is more than adequate for safe, reliable operation.
  • ✅ Mounting Type: 0603 (1608 Metric) Surface Mount is suitable.
  • ✅ Technology: Thick Film construction, as specified.
  • ✅ RoHS Compliance: Marked as ROHS3 Compliant.
Summary: All required specifications are met or exceeded. This resistor is fully suitable for the application.
