HY MFG

Precision Magnetics & OEM Manufacturing

Engineering Reliable Magnetic Components for Power, Energy and Advanced Electronics

HY MFG is an OEM and manufacturing partner specializing in high-frequency electronic transformers, inductors, magnetic components, EI transformers, toroidal transformers, and custom power magnetics.

We support OEMs, engineering companies, distributors and technology manufacturers with both standard and custom magnetic solutions, from engineering development and prototyping to production and assembly.

Our products are designed for demanding applications across new energy, electric vehicles, AI infrastructure, data centers, industrial electronics, LED systems and other power conversion applications.

From Magnetic Design to Production

At HY MFG, we believe the reliability of a magnetic component is determined long before the finished product leaves the production line.

Magnetic performance depends on the fundamentals:

Core material → Magnetic design → Winding → Insulation → Thermal management → Manufacturing process → Testing

Our manufacturing approach focuses on controlling these critical factors to achieve:

• Stable electrical performance
• Controlled temperature rise
• Low acoustic noise
• High insulation reliability
• Consistent production quality
• Long-term operating stability
• Repeatable performance from prototype to mass production

Rather than simply supplying components, we work with customers to develop magnetics that are matched to the electrical and mechanical requirements of the complete system.
