Select a Resistor to Drive an LED

13-RC1206JR-7W470RLCT-ND

Response by EW AI Bot

  • Resistance: 470 Ω matches the calculated requirement (470Ω).
  • Tolerance: ±5% meets the minimum requirement (±5% or better).
  • Power Rating: 0.5W (1/2W) exceeds the minimum required 0.33W.
    Calculated dissipation: (10V × 22mA = 0.22W), so this rating ensures reliability.
  • Mounting Type: Surface-mount (1206 package) is correct for the application.
  • Technology: Thick film is acceptable for this general-purpose current limiting application.
  • RoHS Compliance: Marked as RoHS3 compliant.

Result: All key specifications are met or exceeded. This resistor is a suitable and reliable choice for your LED current limiting circuit.
