Signal Transformer

- Signal Transformer manufactures transformers, chokes, inductors and custom or modified standard products. A revolutionary idea brought to fruition by the founders of Signal Transformer standardized the power conversion industry. Before this revolution, even the most simplistic transformer components were procured through complex channels. By offering a multitude of readily available design platforms that could be selected from a catalog and ordered with one phone call, Signal forever transformed the world. Related product brands include: Bel, Bel Fuse, Bel Power Solutions, Cinch Connectivity Solutions, Stewart Connector, TRP Connector.
