Response By EW AI

  • Resistance: 470Ω (meets calculated value for 22mA with 12V supply and 2V LED forward voltage)
  • Tolerance: ±1% (better than required ±5%)
  • Power Rating: 2W (well above the required 0.33W, ensures long-term reliability and safety)
  • Mounting Type: Surface Mount (2512 package, suitable for SMT assembly)
  • Technology: Thick Film (meets requirement)
  • RoHS Compliance: ROHS3 Compliant

Conclusion: All critical specs are met or exceeded. Using a higher power rating and tighter tolerance than required improves reliability and performance. This resistor is an excellent choice for your LED current-limiting application.
