RES SMD 470 OHM 5% 1/2W 1210

470 Ohms ±5% 0.5W, 1/2W Chip Resistor 1210 (3225 Metric) Automotive AEC-Q200 Thick Film

Response by EW AI Bot

✅ Resistance: 470Ω matches the calculated value for a 12V supply, 2V LED forward voltage, and 22mA desired current [(12V-2V)/0.022A ≈ 455Ω; 470Ω is the next standard value and well within ±5% tolerance].
✅ Tolerance: ±5% meets the requirement for current accuracy and LED brightness consistency.
✅ Power Rating: 0.5W (1/2W) exceeds the minimum required 0.33W. Power dissipated will be (10V × 0.022A) = 0.22W, so 0.5W provides a comfortable safety margin for reliability.
✅ Mounting Type: 1210 surface-mount package fully satisfies the 'Surface Mount' requirement.
✅ Technology: Thick Film is specified and provided.
✅ RoHS Compliance: Marked as ROHS3 Compliant.

Conclusion: All required specifications are met or exceeded. This resistor is suitable and reliable for your LED indicator current-limiting application.
