Custom Transformer Design & Manufacturing Services

Custom Magnetics, Inc. has been in business since 1974 offering innovative solutions for challenging custom transformer applications. We design and manufacture laminated, toroidal, ferrite core, and R-core transformers for customers in a variety of industries, including power generation, transportation, lighting, audio, instrumentation, and communications. From design of to prototype to production, we are well known for supplying the best quality solutions at very competitive prices.

Offered with power ratings from 0.010VA to 9 kVA and frequency ratings from 20 Hz to 500 kHZ, custom transformers can be specified for series or parallel configuration with UL insulation systems from 130°-200° C. Core material options include iron, iron oxides, nickel, magnesium, zinc, and grain oriented silicon steel. Our ISO 9001:2008 -certified facility houses advanced automated systems for High Pot, inductance, resistance, leakage, and surge testing. We offer secondary services, including ultrasonic welding, encapsulating, and vacuum impregnation, providing you with a single source solution for the entire production cycle.

In quantities from prototype to high volume production, we deliver the most precise product to fit your specific application needs, no matter how demanding your technical specifications.
