Pioneering Design and Fabrication
Founded in 1942, we have grown from supplying magnetic components to the U.S. military and NASA to providing tape wound transformer cores used in:
- Power and navigation systems for the Aerospace and Defense industries;
- Transformer assemblies and GFCI’s for electric vehicles and EV charging stations;
- Power supplies and transformers for medical electronic devices and power electronics;
- Communications equipment for the Telecom and Audio industries;
- Voltage monitoring & measuring devices for industrial controls and electric utilities, and many other applications.
We employ a team-based development process – utilizing our technical expertise in material selection, metallurgical processing and fabrication – to engineer the highest quality magnetic cores and custom magnetic components that meet our customers’ most stringent specifications and application requirements.
Applications and Products
Our tape wound toroidal cores (TWTC) utilize a winding configuration that provides a virtually complete magnetic circuit that is unachievable with lamination cores. Our cores are used in:
- Voltage and current transformers,
- Power supplies,
- Motor controls,
- GFCI’s,
- HVAC systems,
- Inductors, converters and inverters,
- Input and output audio signals,
- Computer modems,
- Communications Controls,
- Precision motor controls.
Our tape wound cut cores (TWCC) provide the critical dimensional and weight requirements not available in standard laminations for:
- Transformers and assembly configurations,
- Chokes,
- Current transformers,
- Pulse applications.
