Response By EW AI
- ✅ Resistance: 470Ω (matches calculated value for 12V, 2V LED, 22mA)
- ✅ Tolerance: ±5% (meets required tolerance of ±5% or better)
- ✅ Power Rating: 0.5W (exceeds minimum 0.33W requirement; calculated dissipation is ~0.22W, so ample margin for reliability)
- ✅ Mounting Type: Surface Mount 1210 package (suitable for SMT assembly)
- ✅ Technology: Thick Film (meets requirement for thick or thin film)
- ✅ RoHS Compliance: Yes (ROHS3 Compliant)
All key specifications are met or exceeded. This resistor is well-suited for safely and reliably limiting current to the red LED in your 12V indicator circuit.
