  Ohmite History

  Ohmite Manufacturing Company has been the leading provider of resistive products for high current, high voltage, and high energy applications for over 80 years. The company's full complement of resistor construction includes wirewound, wire element, thick film, and ceramic composition.

  Ohmite Manufacturing Company started operations in a small shop on the west side of Chicago in 1925. Founded by David T. Siegel, the company's focus was to manufacture carbon and wire wound 'lug' resistors for Chicago's growing radio manufacturing industry. As the electronics industry grew and continued to develop, Ohmite continued evolving to service ever changing design requirements. In 1953, the company moved into a newly built factory and offices in Skokie, Illinois.

• Through acquisition, Ohmite added the wirewound capabilities of Memcor-Truohm in 1996 and Ward Leonard Resistors in 1999. Victoreen Components, an experienced specialist in Thick Film technology for high voltage applications, was added to the Ohmite family in 1999.

  In 1998, Ohmite was acquired by Heico Companies LLC; a multinational, U.S. based holding company. The Skokie plant after many years of service was vacated and all operations were moved to Matamoros, Mexico while the Headquarters remained in Rolling Meadows, Illinois. 2006 saw Ohmite continue to grow and enhance its product offerings by acquiring Vishay's Angstrohm Rheostat and Ultronix Precision Resistor divisions.

  Strengthened by the backing of Heico Companies LLC, Ohmite strives to maintain the flexibility needed to handle both large and small requirements. Made to order parts are always considered and new technologies are always being evaluated. Product availability in today's market is critical to the success of our customers. Ohmite's network of international distributors and sales representatives enables us to fulfill the requirements of an increasingly global marketplace.
