Custom R-Core Transformers for Electronic/Magnetic Measuring Equipment & Audio Amplifiers

We provide an expansive variety of custom designed transformers here at Custom Magnetics, Inc. Our work comes backed by nearly 40 years in the business. When a customer in the measuring equipment / audio amplifier industry needed an improvement in their current El laminated transformers, we were pleased to take on the project. Our client was not satisfied with the stray field around their current El laminated transformers, and a toroidal design to replace the El construction unit was too expensive. Our engineers recommended R-Core transformers. With a unique design that includes a small, thin, light size and a high efficiency core, these transformers offer low leakage flux emission and low exciting current. These transformers reduce stray fields in high quality amplifiers, and feature easy bracket mounting. Moreover, we could produce the R-Core units in volume at our facility in India, which further reduce the cost of the units. Our customer accepted these transformers for all the benefits they provide. By switching to R-Core transformers, we were able to fulfill all of our customer's requirements and reduce costs at the same time.
