Response By EW AI

  • Resistance: 470Ω matches the calculated value for 12V - 2V = 10V / 22mA = 454.5Ω (rounded to nearest standard value, 470Ω is correct).
  • Tolerance: ±5% meets the requirement (±5% or better).
  • Power Rating: 0.75W > 0.33W required. Actual dissipation is ~0.22W (10V × 0.022A), so this rating provides good margin for reliability.
  • Mounting Type: 2010 package is surface mount, as specified.
  • Technology: Thick Film, as required.
  • RoHS Compliance: ROHS3 Compliant, as required.

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