Select a Resistor to Drive an LED

MCR50JZHJ471

Response by EW AI Bot

  • Resistance: 470Ω (matches calculated requirement for 12V - 2V @ 22mA)
  • Tolerance: ±5% (meets minimum requirement of ±5% or better)
  • Power Rating: 0.5W (exceeds the minimum required 0.33W; calculated dissipation is 0.22W, so this provides a safe margin)
  • Mounting Type: Surface Mount (2010 package; suitable for SMT assembly)
  • Technology: Thick Film (accepted per requirements)
  • RoHS Compliance: ROHS3 Compliant (meets environmental requirements)

Summary: All key parameters (resistance, tolerance, power rating, mounting, technology, and RoHS) match or exceed the requirements for safely and reliably limiting current to the LED in your application.
