Select a Resistor to Drive an LED

• ✅ Resistance: 470Ω – Matches required value for 22mA @ 12V-2V (10V/0.022A = 454.5Ω, use next standard value up = 470Ω).
• ✅ Tolerance: ±5% – Meets specified tolerance.
• ✅ Power Rating: 0.5W (1/2W) – Exceeds minimum requirement of 0.33W.
  Power dissipated: (0.022A)² × 470Ω ≈ 0.23W, so 0.5W is a safe margin.
• ✅ Mounting Type: Surface Mount (1210 package) – Correct as per requirements.
• ✅ Technology: Thick Film – Acceptable for this application.
• ✅ RoHS Compliance: ROHS3 Compliant – Satisfies environmental requirements.

Result: All specifications are met or exceeded.
Part RMCF1210JT470R is approved for use as an LED current limiting resistor in this design.
