Winatic was initially incorporated in 1963, in Binghamton, NY.  Initially, the company manufactured printer coils primarily for International Business Machines (IBM) until this customer exited that market.

In 1982, Electro Technik Industries, Inc. (ETI) purchased the Winatic Corp. from High Voltage Engineering, Inc. where it remains a subsidiary.  In the year 2000, Winatic’s manufacturing was moved to Costa Rica.


Today,  Winatic manufactures magnetics and transformers primarily for the medical field, but we are proud of our long history of manufacturing high volume, high quality bobbin coils and transformers.

Marrying these two capabilities has allowed us to do high volume production and produce a high reliability product for the medical industry or anyone who cannot skimp on quality.  We look forward to putting our long history and experience to work for you.
