5. Select a Resistor to Drive an LED

• ✅ Resistance: 464Ω (1% tolerance) is extremely close to the calculated 470Ω. This will result in a forward current of ~21.6mA—well within typical LED specs and safe for both LED and circuit reliability.
• ✅ Tolerance: 1% (better than required ±5%). This ensures tightly controlled current and more consistent LED brightness.
• ✅ Power Rating: 0.5W (exceeds minimum requirement of 0.33W). The actual power dissipated (P = I²R ≈ 0.46W * 0.0216A ≈ 0.46W * 0.0216 = 0.0102W) is very low, so this rating is more than sufficient for long-term reliability.
• ✅ Mounting: 1210 SMT package is surface-mount and suitable for automated PCB assembly.
• ✅ Technology: Thick film technology, as required.
• ✅ RoHS Compliance: ROHS3 Compliant.

No mismatches found. This resistor is approved for your LED application. Slightly lower resistance will increase current marginally (to ~21.6mA), which remains safe for most standard red LEDs. The power rating, mounting, and reliability all exceed your requirements.
