Select a Resistor to Drive an LED

SR1206JR-7W470RL-ND

Response by EW AI Bot

  • Resistance: 470Ω matches the calculated requirement for a 12V supply, 2V LED, and 22mA desired current.
  • Tolerance: ±5% is within the required tolerance (±5% or better).
  • Power Rating: 0.5W (1/2W) exceeds the minimum requirement of 0.33W, ensuring safe operation and long-term reliability.
  • Mounting Type: 1206 package is a standard surface mount form factor, meeting the "Surface Mount" requirement.
  • Technology: Thick Film as required for robustness in LED applications.
  • RoHS Compliance: ROHS3 Compliant for environmental and regulatory adherence.
Conclusion: All critical specifications are met or exceeded. This resistor is well-suited for safely and reliably limiting current to your red LED in a 12V indicator circuit.
