CMI's New Standard Product Offerings

Ceramic Magnetics, Inc (CMI) offers a wide variety of Manganese Zinc (MnZn) and Nickel Zinc (NiZn) ferrites specializing in custom powder compositions, custom machined cores as well as standard shapes and sizes.

CMI offers a one-stop solution for applications in power supplies, rotating transformers, pulse transformers, noise suppression and filtering, antennas, sensors and many other magnetic circuit applications.

Our engineering and manufacturing capabilities enable us to develop proof of concept prototypes and then seamlessly ramp up to full scale production quantities. Our assembly department is available to deliver finished product when and where needed.

CMI is a fully integrated manufacturer with both MnZn and NiZn powder processing. Ferrite cores can be manufactured using high volume presses for smaller shapes. Larger shapes can be pressed using 100 ton presses or isostatic pressing. Precision grinding and machining offer tolerances as close as 0.001".

CMI is committed to providing a high level of customer satisfaction through striving for continuous improvement and an empowered workforce.
