Resistor Selection Review
- ✅ Resistance Value: 470Ω (matches calculated requirement)
- ✅ Tolerance: ±5% (meets or exceeds requirement)
- ✅ Power Rating: 0.5W (exceeds minimum 0.33W, ensuring reliable operation)
- ✅ Mounting Type: Surface Mount (0805) (suitable for modern PCB assembly)
- ✅ Technology: Thick Film (acceptable per requirements)
- ✅ RoHS Compliance: ROHS3 Compliant (meets environmental requirements)
Result: All key requirements are met or exceeded. This resistor (Panasonic ERJ-P06J471V) is safe and robust for limiting current to the red LED in your 12V application.
