Custom Transformers & Inductors

(Click on thumbnail to enlarge)

At Endicott Coil Company, Inc., we have been designing and manufacturing custom transformers and inductors for over 50 years. We began in 1954 designing electrical components for IBM, but have expanded into a variety of areas including the very demanding nuclear energy industry. Our transformers can be found in a range of equipment including circuit breakers, automatic switches, fuel sensors, and security systems.

Our experienced engineering staff can design and manufacture any type of transformer including, but not limited to, power, isolation, flyback, and autotransformers. Instead of settling for an off the shelf transformer, we work with our customers to custom design the right transformer or inductor for their specific application. Transformers can be designed with either ferrite cores or laminations between .375″ and 2.125″. Our transformers can be manufactured with power ratings up to 5,000 VA. We also offer a line of standard transformers that can be manufactured as well. We ensure our products meet the highest quality standards by utilizing hipot, resistance, inductance, leak, and surge testing to meet our customers’ ASTM, UL, CSA, VDE, Mil-Spec, and NRC specifications. Please see the table below, or contact us directly. for more details about our custom transformer manufacturing capabilities.
