Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the calculated requirement (470Ω).
• ✅ Tolerance: 1% (better than required ±5%).
• ✅ Power Rating: 0.5W (exceeds minimum required 0.33W).
  • Why this matters: At 22mA, resistor dissipation is (12V–2V)×0.022A = 0.22W, so 0.5W gives ample margin for reliability.
• ✅ Mounting Type: 1206 Surface Mount is appropriate for SMT assembly.
• ✅ Technology: Thick Film (meets requirement).
• ✅ RoHS Compliance: ROHS3 Compliant.

Conclusion: All critical specifications are met or exceeded. This resistor is suitable and recommended for your LED current-limiting application.
