Response By EW AI

  • ✅ Resistance: 470Ω matches required value (470Ω ±5%)
  • ✅ Tolerance: ±5% meets the requirement (±5% or better)
  • ✅ Power Rating: 0.333W (1/3W) meets the minimum (≥0.33W)
    Power dissipated = (10V × 22mA) = 0.22W, so 0.333W is safe.
  • ✅ Mounting Type: 1206 package is Surface Mount, as required
  • ✅ Technology: Thick Film (matches requirement for Thick or Thin Film)
  • ✅ RoHS Compliance: ROHS3 Compliant
All specifications match the requirements. This resistor is suitable for your LED current limiting application.
