Response by EW AI Bot

  • ✅ Resistance: 470Ω (matches calculated requirement of 470Ω for 22mA @ 12V-2V LED drop)
  • ✅ Tolerance: ±0.25% (meets and exceeds the requirement of ±5% or better; tighter tolerance improves consistency)
  • ✅ Power Rating: 0.5W (exceeds the minimum required 0.33W; calculated dissipation is (12V-2V)^2/470Ω ≈ 0.234W, so 0.5W ensures reliability and margin)
  • ✅ Mounting Type: Surface Mount (1206 package, suitable for SMT PCB assembly)
  • ✅ Technology: Thick Film (matches requirement for thick or thin film)
  • ✅ RoHS Compliance: Yes (ROHS3 Compliant—meets environmental requirements)
Summary: All key specifications are matched or exceeded. This resistor is highly suitable for your 12V LED current limiting application.
