Select a Resistor to Drive an LED
CRGP2512F470R
Response by EW AI Bot
- ✅ Resistance: 470Ω (matches calculated requirement)
- ✅ Tolerance: ±1% (better than required ±5%)
- ✅ Power Rating: 2W (well above minimum 0.33W; ensures cool operation and long-term reliability)
- ✅ Mounting Type: Surface Mount (2512 package; suitable for SMD assembly)
- ✅ Technology: Thick Film (matches requirement)
- ✅ RoHS Compliance: ROHS3 Compliant (meets environmental requirements)
All critical requirements are met or exceeded. The selected resistor will safely limit current, fit on a PCB, and operate reliably in your 12V LED application.
Why these specs matter:
- ⚡ Power Rating: The resistor will dissipate ~0.22W (P = (10V x 22mA)), so a 2W rating ensures very low self-heating and excellent reliability margin.
- 🎯 Tolerance: Tight tolerance (±1%) ensures consistent LED brightness and current.
- 🔩 Mounting: SMD 2512 is robust and easy to assemble with standard SMT lines.
