3.3 µHmolded power inductor11 A thermal current16 A saturation current11 mm × 10 mm SMD

RS1040-3R3MS is a 3.3 µH molded power inductor for high-current switching-power rails, rated for 11 A at 40°C temperature rise and 16 A saturation current.

Best for

  • High-current buck converter output inductors
  • Compact DC power rails
  • Power-supply filtering

Avoid if

  • Applications requiring guaranteed RoHS, REACH, MSL, or lifecycle documentation from the supplied source
  • Designs that cannot tolerate inductance reduction under DC bias

Check before use

  • Inductance at operating DC bias
  • Temperature rise in the final PCB layout
  • Peak-current margin relative to the 16 A saturation criterion
  • Recommended 11.5 mm × 3.6 mm PCB pattern
