RMCF1210JT470RCT-ND

Response by EW AI Bot

  • Resistance: 470Ω matches the calculated value for 12V - 2V / 22mA (≈454.5Ω, next standard value is 470Ω).
  • Tolerance: ±5% meets the requirement (±5% or better).
  • Power Rating: 0.5W (1/2W) exceeds the minimum requirement of 0.33W.
    Power dissipated = (10V × 22mA) = 0.22W, so 0.5W is a safe margin.
  • Mounting Type: Surface Mount (1210 package), as required.
  • Technology: Thick Film, meets requirements.
  • RoHS Compliance: ROHS3 Compliant.
All specified requirements are met. This resistor is fully suitable for your 12V red LED application.
