Design and Manufacture

Since 1957, Magnetic Circuit Elements, Inc. (MCE) has been manufacturing reliable magnetic components for customers who value performance and precision. Every transformer, inductor, and choke we build is designed and tested in our Salinas, California facility. Our goal is simple—deliver high-quality magnetic solutions that meet your exact specifications and stand the test of time.

With decades of experience, MCE continues to be a dependable source for transformers, inductors, and chokes used in mission-critical applications. Whether you need a push-pull output transformer for clean and efficient power conversion, an adjustable inductor for fine-tuning circuit performance, or a common mode choke for effective noise suppression, we have the knowledge and equipment to produce what your project demands.

Each component is made in the U.S. with strict quality control and 100% final testing. Our engineers and production specialists work closely with you to develop custom or standard magnetic parts that fit seamlessly into your design.

Our engineers design magnetic components for both standard and custom applications. Whether you need a single prototype or full production quantities, we can meet your requirements. Each product is built to exact performance specifications and tested for accuracy, insulation, and safety.

We specialize in precision winding, magnetic circuit design, and performance matching for your system. If you need flexibility during product testing or tuning, we offer an adjustable inductor that lets you fine-tune inductance levels easily. That kind of practicality helps reduce rework and saves time during development.

Every MCE part goes through a thorough final inspection, so what you receive is ready to perform as expected.

Our components are used in systems where reliability is critical.

• Aerospace – High-frequency transformers and noise suppression coils for navigation and flight systems.
• Defense – Power conversion transformers and inductors built to military-grade standards.
• Medical – Compact and reliable magnetic components for diagnostic and monitoring equipment.
• Industrial – Transformers and chokes that support automation and control systems.
• Communications – Common mode chokes and signal transformers for clean transmission and reduced interference.
• Audio – Push-pull output transformers for high-fidelity sound reproduction and stable output.

No matter the application, MCE components are made to perform under tough conditions.

Every part that leaves our facility is fully tested and inspected. Our manufacturing process follows strict quality protocols to guarantee precision and durability. Whether it’s a single prototype or a full production run, our team makes sure your specifications are met accurately.
