CRGH0805J470R
Response by EW AI Bot
- ✅ Resistance: 470Ω ±5% — Matches calculated requirement for desired current through the LED.
- ✅ Tolerance: ±5% — Meets or exceeds the specified tolerance requirement.
- ✅ Power Rating: 0.333W (1/3W) — Exactly meets the minimum required power rating for safe long-term operation.
Power dissipated in resistor: (12V - 2V)2 / 470Ω ≈ 0.213W, so 0.333W is sufficient. - ✅ Mounting Type: Surface Mount (0805) — Suitable for SMT assembly as required.
- ✅ Technology: Thick Film — Acceptable for this application.
- ✅ RoHS Compliance: ROHS3 Compliant — Meets environmental requirements.
All required specifications are met. This resistor is a suitable and reliable choice for your 12V red LED current limiting application.
