Select a Resistor to Drive an LED

RC1206FR-7W470RL

Response by EW AI Bot

  • Resistance: 470Ω matches the calculated value needed for 12V→2V/22mA LED current limiting.
  • Tolerance: 1% (better than required ±5%).
  • Power Rating: 0.5W (exceeds 0.33W minimum, ensuring reliability and cooler operation).
  • Mounting Type: 1206 Surface Mount package, as required.
  • Technology: Thick Film (matches requirement).
  • RoHS Compliance: ROHS3 Compliant.
Summary:
All key specifications are met or exceeded. This resistor is fully suitable for safely limiting current to a red LED at 22mA from a 12V supply in a surface-mount application. Good choice!
