Select a Resistor to Drive an LED
A126441TR-ND
Response by EW AI Bot
- ✅ Resistance: 470Ω matches the calculated requirement for 22mA LED current (using (12V-2V)/22mA = 454.5Ω, rounded to standard value 470Ω).
- ✅ Tolerance: ±5% meets the requirement ("±5% or better").
- ✅ Power Rating: 0.333W (1/3W) meets the minimum requirement of ≥0.33W.
Check: Power dissipated = (I²)R = (0.022²)×470 ≈ 0.227W, which is well within 0.333W rating. - ✅ Mounting Type: 0805 package is a standard surface-mount format.
- ✅ Technology: Thick Film, as required.
- ✅ RoHS Compliance: ROHS3 Compliant.
Conclusion: Approved for use as an LED current-limiting resistor in this application.
