Through its wholly owned subsidiary Payton America, Payton Planar Magnetics Ltd. of Israel marks another significant step in its strategic growth program with the acquisition of SI Manufacturing in Anaheim, California. The deal closed in October 2025. Established in 1952 and with estimated annual sales of $8 million, SI specializes in the production and sale of electronic coils, assembly of power supplies, and manufacturing of magnetic components.

“We are pleased to complete the acquisition of SI, our first joint acquisition with FIMI Opportunity Funds, establishing the Group’s first presence on the West Coast. By doing so, we are executing our growth strategy, which combines organic expansion with synergistic acquisitions. The acquired company has a diverse customer base in defense, aerospace, aviation, transportation, and power supply assembly. Together with Payton Group’s strong experienced engineering team, we anticipate joint growth opportunities for the existing Group companies and SI. We believe this acquisition will contribute to the expansion of our international operations and accelerate the Group’s growth.”
As a technology, planar magnetics can excel in bringing new capabilities to design engineers in high-frequency power electronics. Unlike traditional transformers, planar transformers employ windings that are intricately crafted from flat copper foil lead frames or seamlessly integrated into a PCB. The meticulously designed windings are then sandwiched between thin, lightweight ferrite cores. The technology is widely used in high-frequency battery chargers, inverters, hybrid vehicles, telecom rectifiers, solar and wind power, medical and defense applications, inductance charging and welding equipment.


Publicly traded on the Euronext stock exchange in Brussels, Payton Planar designs, manufactures and markets Planetics, its customized line of planar transformers, conventional transformers and inductors to original equipment manufacturers and their suppliers of power electronics. Based in Rishon LeZion south of Tel Aviv, the group employs about 170 people with operations in Israel, USA and the UK. HiMag Planar Magnetics in Quedgeley, Gloucestershire is the UK subsidiary, while Payton America serves North and South America from its site in Deerfield Beach, Florida. See www.paytongroup.com.
