3 Phase Inductors

Our custom three-phase inductors are used in applications including aviation, power conditioning, renewable energy power conversion and high-power battery charging, to name a few.

Designs may incorporate foil and high-temperature windings, strip-wound amorphous metal, ferrite or high-grade steel cores. Dimensions and mountings are tailored to suit your specific need. Inductors can also be incorporated into the primary winding of a transformer to save both cost and space.

High Frequency & Switch Mode Inductors

Understanding SMPS fundamentals is essential when optimizing a inductor design for smaller size, cooler operation and lower losses. We've been designing and building custom Switch Mode Power Supply magnetics for over 25 years. From design concept to delivery, you can rely on our expertise to help you minimize your risk and achieve a high performance product.

DC & AC Inductors, Chokes & Reactors

We design and build our inductors and chokes with state-of-the-art materials including powdered metals, ferrites, amorphous metals and silicon & nickel iron materials. In-house gapping capability allows us to meet specific inductance specifications and our collaborative approach to design allows us to deliver applications with results in optimal performance in the most efficient package.

Aviation & 400Hz Inductors

We build custom applications for many industries including the ones with tough, demanding Aviation and Marine environments. We know special consideration must be given to vibration, moisture, weight, contamination and qualification. Unique winding configurations, high-efficiency cores, high-strength and non-nutrient encapsulants.

That's why we work collaboratively with you and your technical personnel to to develop the optimal solution for your complex requirement.
