OEM manufacturer of high-frequency transformers, chokes, coils, and inductors


Our ferrite core transformers, both through-hole and SMD type, have up to 500W with a frequency of 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. We offer a comprehensive 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


Our inductors can be designed to operate over a wide range of frequencies, input voltages, and inductance values. They can be varnish impregnated, molded, or potted with epoxy in an enclosure. Magnetic inductors are available with fly leads, PCB pins, solder terminals, or screw terminals. Our magnetic inductors can be fixed, shielded, and tordial and use many standard mounting styles. We provide the following magnetic inductors:

  • Air core
  • Common mode
  • Ferrite core
  • Fixed inductors
  • Powdered iron core
  • Power line chokes/filters
  • Shielded inductors
  • Toroidal inductors


Syrma SGS Technology’s ferrite core transformers are typically produced up to 500W with a typical frequency of up to 300KHz. Ferrite cores are available in many shapes, including E, EC, EP, ETD, PC (pot), PQ, RM, RS (slab), rods, TC (toroidal), and U. We manufacture both through-hole and SMD type transformers. We manufacture a full line of magnetic transformers:

  • Ferrite/metal powder/nano-crystalline E core transformers
  • High-frequency toroidal transformers
  • Impedance matching transformers
  • Pot core/RM transformers
  • Other geometries EI/EF/ER/EFD/EP
  • Signal transformers
