Response By EW AI
- ✅ Resistance: 470Ω — matches calculated requirement for 22mA with 12V and 2V LED drop.
- ✅ Tolerance: ±5% — meets specification (±5% or better).
- ✅ Power Rating: 0.333W (1/3W) — meets or exceeds required ≥0.33W.
(Actual dissipation is ~0.22W: (10V × 22mA). Good margin for reliability.) - ✅ Mounting Type: Surface Mount (0603 package) — suitable for SMD assembly.
- ✅ Technology: Thick Film — acceptable per requirements.
- ✅ RoHS Compliance: Yes — "RoHS3 Compliant".
All key specs are met. This part is suitable and recommended for your LED current limiting application.
