Power Inductors & Chokes

API Technologies offers a family of ruggedly manufactured toroidal inductors designed to filter out noise currents from various electrical and electronic power control circuits.  After years of research and development, we produces inductors that utilize newly developed materials, designs, and processes, setting new standards for performance in several areas of the inductors market.

Every API inductor is tailored and optimized for specific applications.

  • Precision wound heavy-duty toroidal inductors
  • Up to 100 amps, standard
  • Lighting dimmers – low wattage residential to higher wattage commercial, motor controls, SCR controls and line filters
  • Stores energy as a magnetic field, can delay and reshape alternating current
  • Semi or full epoxy molded, horizontal and vertical mounting
  • Suitable for EMI/RFI noise filtering
  • Filter out ripple in DC rectification circuits
  • Noise rejection
  • Power filtering from DC to 50MHz
  • For switch mode power regulator controls and other energy storage circuits
  • Lighting dimmers – low wattage residential to higher wattage commercial, motor controls, SCR controls and line filters
