Response By EW AI

  • ✅ Resistance: 470Ω (meets calculated 470Ω requirement for 22mA through the LED)
  • ✅ Tolerance: ±1% (better than required ±5%)
  • ✅ Power Rating: 0.5W/1/2W (exceeds required ≥0.33W; actual power dissipation is 0.22W)
  • ✅ Mounting Type: Surface Mount 1206 package
  • ✅ Technology: Thick Film (matches requirement)
  • ✅ RoHS Compliance: ROHS3 Compliant
No mismatches found. This resistor is fully suitable for your LED current limiting application. Good choice!
