Industrial Magnetic Chokes

Magnetic components (transformers, inductors, and chokes) are key elements of lighting, communication, consumer electronics, home appliances, defense, automotive, and computers. Our Ferrite core transformers, both through-hole and SMD type, have up to 500W with a frequency up to 300KHz. Our inductors operate over a wide range of frequencies, input voltages, and inductance values. Our magnetic chokes protect circuits from high-frequency alternating current and allow for low-frequency direct current.

A choke is a specialized inductor, usually consisting of a coil of insulated wire wound on a magnetic core. It’s used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC), with minimal power loss. Construction of coil devices varies widely in number of turns of magnet, tefzel, and litz wires. Most windings are automatically wound on thermoplastic or thermoset bobbins, which offer excellent ground insulation, the most effective use of window area, and the greatest amount of control for through-hole or surface mounting.

Core materials used in magnetics include silicon iron, nickel alloys, metallic glass, cobalt alloys, and ferrite to powdered iron. We offer a wide catalog of common mode magnetic chokes, including toroidal core, epoxy-encapsulated, and three-phase chokes, including:

  • High current chokes for industrial welding
  • Large volume chokes for EMI/RFI filters
  • Bobbin wound, toroidal, SMT, and PTH
