5. Select a Resistor to Drive an LED

✅ Resistance: 470 Ω is within the acceptable range of 430 Ω to 470 Ω and is a valid choice for a 12 V red LED with 2 V forward voltage and 22 mA target current.

✅ Tolerance: ±5% meets the requirement of ±5% or tighter.

✅ Power rating: 0.75 W exceeds the minimum required ≥0.5 W, providing adequate thermal margin.

✅ Type: Thick Film matches the required resistor type.

✅ Mounting type / package: Surface-mount, 1210 package matches the required form factor.

✅ Operating temperature: -55°C to +155°C exceeds the required -55°C to +125°C or wider.

✅ RoHS compliance: ROHS3 Compliant satisfies the RoHS requirement.

All required specifications are satisfied. The component is approved for this LED current-limiting resistor application.
