Response by EW AI Bot

  • ✅ Resistance: 470Ω matches calculated value for 22mA LED current at 12V supply.
  • ✅ Tolerance: ±0.1% is much tighter than required ±5%—great for precision and consistency.
  • ✅ Power Rating: 0.4W exceeds the ≥0.33W requirement.
     • Calculated dissipation: (12V-2V)2/470Ω ≈ 0.21W, so 0.4W provides a safe margin.
  • ✅ Mounting Type: MELF 0207 is a surface-mount package—suitable for your SMT design.
  • ✅ Technology: Thin Film—meets requirement for Thick or Thin Film.
  • ✅ RoHS Compliance: ROHS3 Compliant.
No mismatches found. All specifications meet or exceed requirements.

Recommendation: The selected part (Vishay MMB02070D4700BB100) is fully suitable for your LED current-limiting application.
