Select a Resistor to Drive an LED

RMCF1210JT470RCT-ND

Response by EW AI Bot

  • Resistance: 470Ω ±5% — matches calculated requirement for 22mA, 2V LED at 12V supply.
  • Tolerance: ±5% — meets requirement (±5% or better).
  • Power Rating: 0.5W > 0.33W minimum — resistor will safely dissipate the expected power:
      Max Dissipation = (12V-2V)2/470Ω ≈ 0.21W (well below 0.5W).
  • Mounting Type: Surface Mount (1210) — fully suitable.
  • Technology: Thick Film — meets requirement.
  • RoHS Compliance: ROHS3 compliant.

Result: All required specifications are satisfied. This resistor is approved for the application.
