Select a Resistor to Drive an LED

PCR1206-470RJ1

Response by EW AI Bot

  • Resistance: 470Ω matches the calculated value for 22mA LED current (using (12V-2V)/22mA = 454Ω, next E24 value = 470Ω).
  • Tolerance: ±5% meets the requirement.
  • Power Rating: 0.333W (1/3W) meets the minimum required rating of 0.33W.
        • Power dissipated = (Current²) × Resistance = (0.022A)² × 470Ω ≈ 0.227W, well within the limit.
  • Mounting Type: Surface Mount (1206 package) is suitable.
  • Technology: Thick Film is acceptable per the requirements.
  • RoHS Compliance: ROHS3 Compliant.

All specified criteria are met. This resistor is suitable for your LED current-limiting application.
