Components for Magnetic Products

Syrma provides a full range of custom magnetic components (chokes, inductors, and transformers). 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 chokes protect circuits from high-frequency alternating current and allow for low-frequency direct current. Our engineering team draws upon 20+ years of experience at the forefront of analog design and manufacturing to ensure a streamlined end-to-end product cycle, from prototyping and testing through high-volume production.

We operate two sites in India that offer dedicated magnetics capabilities, including our dedicated 30K square foot facility, ideally situated in the technology corridor between Bengaluru and Chennai. Our facilities are ISO certified and manufacture products to global safety standards, including UL, CSA, and VDE. We have extensive experience in working with a spectrum of composite materials and wire sizes. Our team specializes in epoxy potting, UV curing, laser marking, and conformal coating. Our design process includes detailed requirements gathering and documentation, process validation, failure mode and effects analysis (FMEA), advanced product quality planning (APQP), alternate material sourcing, and a production plan with airtight quality control.

We design custom bobbins, plastics, and machining of metal parts for final assembly. Core materials used in magnetics include silicon iron, nickel alloys, metallic glass, cobalt alloys, and ferrite to powdered iron. Construction of coil devices varies widely in the number of turns of 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 greatest amount of control for through-hole or surface mounting.
