Magnetic Chokes


Chokes are specialized magnetic inductors, commonly used to regulate raw current and prevent electromagnetic or radio frequency interference from harming electric circuits.

Syrma manufactures a full range of industrial magnetic chokes including:

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

Common mode choke SKU# ST454

Electrical Characteristics

A choke is a specialized inductor, usually consisting of a coil of insulated wire wound on a magnetic core. It is used to block higher-frequency alternating current (AC) in an electrical circuit, while passing lower-frequency or direct current (DC), with minimal power loss.

Physical Characteristics

We offer a wide catalog of common mode chokes, including toroidal core, epoxy-encapsulated and three phase chokes.
