Response By EW AI
- ✅ Resistance: 470Ω – Matches the calculated requirement (470Ω).
- ✅ Tolerance: ±0.1% – Exceeds the required ±5% or better, giving greater precision.
- ✅ Power Rating: 0.375W (3/8W) – Exceeds the minimum requirement of ≥0.33W. For your design, power dissipated = (12V-2V)×22mA = 0.22W, providing a good safety margin.
- ✅ Mounting Type: 0603 SMD – Surface mount as specified.
- ✅ Technology: Thin Film – Acceptable (meets Thick Film or Thin Film criterion).
- ✅ RoHS Compliance: ROHS3 Compliant.
Summary: All key parameters (resistance, tolerance, power rating, mounting, technology, RoHS) are met or exceeded. This is a highly suitable choice for your LED current limiting application.
