Select a Resistor to Drive an LED

13-RC1206JR-7W470RLTR-ND

Response by EW AI Bot

  • Resistance: 470Ω (matches calculated requirement for 22mA with 12V supply and 2V LED drop)
  • Tolerance: ±5% (meets minimum requirement of ±5% or better)
  • Power Rating: 0.5W (exceeds the required ≥0.33W; calculated dissipation is (10V*0.022A)=0.22W, so 0.5W is ample margin for long-term reliability)
  • Mounting Type: Surface Mount, 1206 package (suitable for most PCB assembly processes and compact designs)
  • Technology: Thick Film (acceptable per requirements)
  • RoHS Compliance: ROHS3 Compliant
Result: All specifications match or exceed requirements. This resistor is well-suited for limiting current to a red LED in your 12V indicator application.
