Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω – Matches the calculated need for a 22mA current with 12V supply and 2V LED forward voltage.
  Why it matters: Ensures correct LED brightness and prevents overcurrent damage.
• ✅ Tolerance: ±5% – Meets the requirement for ±5% or better.
  Why it matters: Controls current variation and LED brightness consistency.
• ✅ Power Rating: 0.333W (1/3W) – Exactly meets the specified minimum of 0.33W.
  Why it matters: Resistor will safely dissipate the power (0.22W typical in this circuit) with sufficient margin for reliability.
• ✅ Mounting Type: Surface Mount (0603 package) – Matches requirement.
  Why it matters: Suitable for automated assembly and compact PCB layouts.
• ✅ Technology: Thick Film – Meets requirement for Thick or Thin Film.
• ✅ RoHS Compliance: ROHS3 Compliant – Environmentally compliant as required.

Conclusion: All specifications are met; this resistor is fully approved for your design.
