Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω matches the required value for a 12V to 2V drop at 22mA (calculated: 454.5Ω, nearest E24 = 470Ω).
• ✅ Tolerance: ±5% meets the requirement (±5% or better).
• ✅ Power Rating: 1W far exceeds the minimum of 0.33W. The actual power dissipated is P = I²R = (0.022A)² × 470Ω = 0.227W, so this resistor is safely derated for long-term reliability.
• ✅ Mounting Type: 1206 Surface Mount package is suitable.
• ✅ Technology: Thick Film, which meets the specified requirement.
• ✅ RoHS Compliance: ROHS3 Compliant.

All key specifications are met or exceeded. This resistor is a robust and reliable choice for your 12V red LED current-limiting application.
