Magnetic components (chokes, inductors, and transformers) are essential lighting, communication, consumer electronics, home appliances, defense, automotive, and computers. Syrma SGS Technology’s 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. 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.
The construction of coil devices varies widely in the number of turns of the magnetic, 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 most significant 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 comprehensive catalog of common-mode magnetic chokes, including toroidal core, epoxy-encapsulated, and three-phase chokes, including:
