Select a Resistor to Drive an LED

RC1206JR-7W470RL

Response by EW AI Bot

  • Resistance: 470Ω ±5% (matches required 470Ω ±5%)
  • Power Rating: 0.5W (meets/exceeds required ≥0.33W; actual dissipation is ~0.22W, so this is safe with margin)
  • Tolerance: ±5% (meets requirement of ±5% or better)
  • Mounting: 1206 Surface Mount (matches SMT requirement)
  • Technology: Thick Film (acceptable per requirements)
  • RoHS Compliance: ROHS3 Compliant (meets requirement)

Summary: All required specifications are met. This resistor is well-suited for safely limiting current to a red LED in a 12V system. The power rating provides margin for reliability and the SMT package is appropriate for modern PCB assembly.
