5. Select a Resistor to Drive an LED

• ✅ Resistance: 464Ω (Required: 470Ω ±5%)
  - The selected value (464Ω) is within the required ±5% tolerance range of 470Ω (446.5Ω to 493.5Ω), so it is suitable for targeting ~22mA through the LED.
• ✅ Tolerance: ±0.05% (Required: ±5% or better)
  - Much tighter than required, ensuring precise current regulation.
• ✅ Power Rating: 0.5W (Required: ≥0.33W)
  - Exceeds the minimum specification, providing greater reliability and safety margin.
• ✅ Mounting Type: Surface Mount (1206 package)
  - Fully meets the design requirement for surface mounting.
• ✅ Technology: Thin Film
  - Acceptable, as either Thick Film or Thin Film is suitable.
• ✅ RoHS Compliance: Yes
  - Environmentally compliant as requested.

Summary: All essential specifications are met or exceeded. The selected resistor is well-suited for reliable, safe LED current limiting in this 12V indicator circuit.
