Response By EW AI

  • Resistance: 470Ω matches the calculated requirement (470Ω for 22mA at 12V–2V drop).
  • Tolerance: 1% (better than required ±5%) provides more precise current control.
  • Power Rating: 0.5W (exceeds minimum required 0.33W). Power dissipated will be P = (10V × 0.022A) = 0.22W, well within the rating.
  • Mounting Type: 1206 SMD package is a standard surface-mount size, suitable for your application.
  • Technology: Thick Film (matches requirement of Thick Film or Thin Film).
  • RoHS Compliance: ROHS3 Compliant (meets your environmental requirement).

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