- ✅ Resistance: 470Ω matches the requirement (calculated value for 22mA with 2V Vf from 12V supply).
- ✅ Tolerance: ±5% meets the specification (±5% or better).
- ✅ Power Rating: 0.333W (1/3W) is exactly at the required minimum of ≥0.33W. For this application, the resistor will dissipate P = (10V × 22mA) = 0.22W, so this rating is sufficient with margin for reliability.
- ✅ Mounting Type: Surface Mount (0603 package), as required.
- ✅ Technology: Thick Film, which is allowed by the spec.
- ✅ RoHS Compliance: ROHS3 compliant as required.
No mismatches found. This resistor is well-suited for your LED current limiting application.
