Response By EW AI

  • Resistance: 470Ω (matches required 470Ω, calculated for 22mA with 2V LED, 12V supply)
  • Tolerance: ±5% (meets requirement of ±5% or better)
  • Power Rating: 0.333W (1/3W) (meets minimum required 0.33W; actual power dissipated: (10V x 0.022A) = 0.22W, so 0.333W is sufficient margin)
  • Mounting Type: 0805 Surface Mount (matches the surface-mount requirement)
  • Technology: Thick Film (meets 'Thick Film or Thin Film' requirement)
  • RoHS Compliance: ROHS3 Compliant (meets environmental requirements)

All required specifications are met. This part is suitable for your LED current limiting application.
