Response By EW AI

  • ✅ Resistance: 470Ω matches the calculated requirement (470Ω for 22mA at 12V-2V=10V across resistor).
  • ✅ Tolerance: ±5% meets the requirement of ±5% or better.
  • ✅ Power Rating: 0.333W (1/3W) meets the minimum 0.33W requirement. Calculated dissipation is 0.22W, so this is suitable.
  • ✅ Mounting Type: 0603 SMD is a standard surface mount package.
  • ✅ Technology: Thick Film, as required.
  • ✅ RoHS Compliance: ROHS3 compliant.
No mismatches found: This resistor is fully suitable for your LED current limiting application.
