Select a Resistor to Drive an LED
CRGH1206J470R
Response by EW AI Bot
- ✅ Resistance: 470Ω (matches calculated value for 22mA with 12V supply and 2V LED drop)
- ✅ Tolerance: ±5% (meets requirement of ±5% or better)
- ✅ Power Rating: 0.5W (exceeds minimum requirement of 0.33W)
Power dissipated = (12V-2V)×22mA ≈ 220mW, well below the part's rating - ✅ Mounting Type: Surface Mount (1206 package is standard for SMT)
- ✅ Technology: Thick Film (meets requirement; suitable for general current-limiting)
- ✅ RoHS Compliance: Yes (ROHS3 Compliant)
Result: All critical specifications are met or exceeded for reliable and safe operation in your LED current-limiting application.
