Response By EW AI
- ✅ Resistance: 470Ω (matches calculated value for 12V → 2V @ 22mA)
- ✅ Tolerance: ±1% (better than required ±5%)
- ✅ Power Rating: 0.5W (exceeds minimum required 0.33W; circuit only dissipates ~0.22W)
- ✅ Mounting Type: Surface Mount (1206 package, as required)
- ✅ Technology: Thick Film (meets requirement)
- ✅ RoHS Compliance: Yes (ROHS3 Compliant)
All required specifications are met or exceeded. This resistor is an excellent and reliable choice for safely limiting current to a red LED in your 12V application.
