About Triad Magnetics

Pioneering Custom Magnetics & Transformer Solutions Globally

For over 75 years, Triad Magnetics has engineered and manufactured advanced magnetic components that power consumer, commercial, industrial, medical, and renewable energy electronics worldwide. We take immense pride in our engineering heritage while continually expanding our custom design capabilities and global manufacturing infrastructure to meet the evolving demands of OEM buyers.

Our commitment to engineering excellence makes the difference. With more than 1,000 standard catalog items, an extensive global distributor network, and fully customizable design capabilities, Triad Magnetics provides reliable, compliant, and cost-effective magnetic solutions tailored precisely to your application requirements.

Engineering Design Innovation & Custom Prototyping

While our standard catalog serves thousands of power conversion, audio, and industrial applications worldwide, our core strength lies in custom magnetics design. Located in Perris, California, our engineering headquarters houses sophisticated electromagnetic simulation tools, environmental testing laboratories, and rapid prototyping capabilities.

Our design process is built around collaborative engineering. Senior engineers work directly with your design teams to overcome space constraints, thermal dissipation requirements, EMI/RFI interference, and stringent international safety standards. Whether you require minor modifications to a catalog transformer or a ground-up magnetic assembly, Triad Magnetics delivers optimized prototypes quickly and efficiently.

World-Class Global Manufacturing Footprint

Triad Magnetics operates state-of-the-art manufacturing facilities in the United States and the Philippines. By leveraging advanced cellular manufacturing methods, automated winding systems, and lean production techniques, we shorten lead times while eliminating material handling inefficiencies.

Our flexible manufacturing capabilities cater to diverse procurement strategies—from small prototype batches to high-volume OEM production runs exceeding millions of units annually.

Standard & Custom Product Portfolio:

ISO 9001:2015 Certification & Stringent Quality Controls

Reliability is non-negotiable in critical power systems. Triad Magnetics operates under a strict ISO 9001:2015 certified Quality Management System. Every component undergoes rigorous in-process inspections, 100% automated electrical testing (including Hi-Pot dielectric testing, inductance measurement, and turns ratio validation), and pre-shipment audits.

Our commitment to quality allows many of our key OEM customers to bypass incoming inspections entirely, accelerating their production timelines and lowering overall procurement costs.
