Response By EW AI
- ✅ Resistance: 470Ω — matches calculated value
- ✅ Tolerance: ±0.1% — much better than required ±5%
- ✅ Power Rating: 0.4W — exceeds minimum requirement of 0.33W
At 22mA, actual power dissipated is: P = I²R = (0.022A)² × 470Ω ≈ 0.227W, well within rating - ✅ Mounting Type: Surface Mount (1206 package)
- ✅ Technology: Thin Film — suitable and meets requirement
- ✅ RoHS Compliance: Yes (ROHS3 Compliant)
All key requirements are met or exceeded. This resistor is an excellent and reliable choice for your 12V LED indicator circuit.
