- ✅ Resistance: 470Ω — Correct value for 22mA LED current with 12V→2V drop.
- ✅ Tolerance: ±5% — Meets or exceeds the ±5% requirement.
- ✅ Power Rating: 0.333W (1/3W) — Meets the ≥0.33W minimum; calculated dissipation is (10V × 0.022A = 0.22W), so this rating provides a good safety margin.
- ✅ Mounting Type: Surface Mount (0603) — Fully suitable for SMD assembly.
- ✅ Technology: Thick Film — Acceptable per requirements.
- ✅ RoHS Compliance: RoHS3 Compliant — Environmentally suitable.
All critical specifications are satisfied. This part is well-suited for the design and will ensure reliable LED operation.
