Response By EW AI

  • ✅ Resistance: 470Ω (matches required 470Ω)
  • ✅ Tolerance: ±5% (meets required ±5% or better)
  • ✅ Power Rating: 0.5W (exceeds required ≥0.33W; calculated dissipation is ~0.22W, so this is safe)
  • ✅ Mounting Type: 1206 Surface Mount (complies with surface mount requirement)
  • ✅ Technology: Thick Film (meets thick/thin film requirement)
  • ✅ RoHS Compliance: ROHS3 Compliant (environmentally suitable)
All specifications are met or exceeded. This resistor is well-suited for safely and reliably limiting current to a red LED in your 12V design.
