ERJ-HP6F4530V

Response by EW AI Bot

  • ✅ Resistance: 453Ω (1% tolerance). This is very close to the calculated 470Ω and within the ±5% required range. This will give ~22mA, slightly more than 21.3mA (10V/470Ω), but still within LED spec for brightness and safety.
  • ✅ Tolerance: ±1%. This exceeds the requirement for ±5% or better, providing higher precision.
  • ✅ Power Rating: 0.5W (1/2W). This exceeds the required ≥0.33W, ensuring the resistor safely dissipates the expected power (~0.215W @ 22mA).
  • ✅ Mounting Type: Surface Mount (0805). Fully matches SMT requirement.
  • ✅ Technology: Thick Film. Meets the requirement for Thick Film or Thin Film.
  • ✅ RoHS Compliance: ROHS3 Compliant (per DigiKey data).
No mismatches found. This resistor is safe, reliable, and suitable for your 12V red LED current limiting application.
