Response By EW AI

  • ✅ Resistance: 464Ω is within the required 470Ω ±5% range (446.5Ω–493.5Ω). This will yield ~21.6mA, very close to 22mA target.
  • ✅ Tolerance: ±0.5% is much tighter than the required ±5%.
  • ✅ Power Rating: 0.333W (1/3W) meets the required minimum of 0.33W.
    Power dissipated: (10V × 0.0216A = 0.216W) < 0.333W.
  • ✅ Mounting Type: 0603 SMD package is suitable for surface mount.
  • ✅ Technology: Thick Film, as specified.
  • ✅ RoHS Compliance: ROHS3 Compliant.
No mismatches found. This part is fully suitable for your LED current limiting application.
