Resistor Selection Review

  • Resistance: 470Ω (matches calculated value for 22mA at 12V-2V drop)
  • Tolerance: ±5% (meets requirement of ±5% or better)
  • Power Rating: 0.333W, 1/3W (meets requirement of ≥0.33W)
  • Mounting Type: Surface Mount 0603 (suitable for SMD assembly)
  • Technology: Thick Film (acceptable)
  • RoHS Compliance: Yes (ROHS3 Compliant)

All required specifications are fulfilled.

Conclusion: This resistor is approved for use in the 12V red LED current-limiting application.
