541-10643-2-ND

Response by EW AI Bot

  • Resistance: 470Ω (matches calculated value for 12V → 2V @ 22mA)
  • Tolerance: ±1% (better than required ±5%)
  • Power Rating: 0.5W (exceeds minimum required 0.33W; circuit only dissipates ~0.22W)
  • Mounting Type: Surface Mount (1206 package, as required)
  • Technology: Thick Film (meets requirement)
  • RoHS Compliance: Yes (ROHS3 Compliant)

All required specifications are met or exceeded. This resistor is an excellent and reliable choice for safely limiting current to a red LED in your 12V application.
