541-470TTR-ND

Response by EW AI Bot

  • ✅ Resistance: 470Ω (matches required 470Ω for 22mA @ 12V with 2V LED drop)
  • ✅ Tolerance: ±1% (better than required ±5%, so will ensure consistent LED brightness)
  • ✅ Power Rating: 0.5W (exceeds minimum required 0.33W; actual dissipation is ~0.22W, providing a good safety margin for reliability)
  • ✅ Mounting Type: Surface Mount (0805 SMD package, suitable for automated assembly)
  • ✅ Technology: Thick Film (matches requirement)
  • ✅ RoHS Compliance: Yes (ROHS3 Compliant)
Result: All selection criteria are met or exceeded—this resistor is well-suited for your 12V red LED current-limiting application.
