E Craftsmen
As an essential business, it is our intention to continue normal operations to the greatest extent possible. This video is a great introduction into who we are and what we do!.Custom-designed transformers and inductors made to match your unique application.

I would like to express our appreciation for your efforts in making this a successful project for us, especially to George for his expertise in refining the design and to your production for executing flawlessly.We achieved very high levels of consistency in our build, at least in part due to the very consistent performance of the magnetics.

Since 1956, E Craftsmen Corporation (operating as Electronic Craftsmen) has earned a reputation for innovation, superior quality and process excellence. At our 23,000 sq ft facility in Waterloo, Ontario (Canada), we design & build a broad range of specialty and custom transformers, inductors, chokes and reactors for use in power electronics applications.
Whether you need a custom solution or a simple build-to-print, we have the design skills and manufacturing know-how to turn your demanding specification into a precision component that works right, the first time. Our reliable, innovative designs are all backed with a 5 year warranty.

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.Our inductors utilize state-of-the-art materials including powdered metals, ferrites, amorphous metals and silicon & nickel iron materials.
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.
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.
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.
