  • ✅ Resistance: 470Ω – matches calculated value for 22mA LED current with 12V supply (R = (12V - 2V) / 0.022A = 454.5Ω, use standard 470Ω).
  • ✅ Tolerance: ±0.1% – tighter than required ±5%, ensures consistent LED brightness.
  • ✅ Power Rating: 0.5W (≥0.33W required) – provides a strong safety margin for calculated dissipation (~0.48W × 0.022A = 0.47W, but actual with 470Ω is (0.022A)2 × 470Ω = 0.227W).
  • ✅ Mounting: Surface Mount (2010 size) – suitable for automated assembly and thermal handling.
  • ✅ Technology: Thin Film – meets or exceeds thick film/standard requirements; offers high precision and stability.
  • ✅ RoHS Compliance: ROHS3 Compliant.
All required specifications are met or exceeded. This resistor is suitable for your LED indicator design.
