Ohmite History Ohmite Manufacturing Company been leading provider resistive products high current, high voltage, high energy applications over years. company's full complement resistor construction includes wirewound, wire element, thick film, ceramic composition. Ohmite Manufacturing Company started operations small shop west side Chicago 1925. Founded David Siegel, company's focus manufacture carbon wire wound "lug" resistors Chicago's growing radio manufacturing industry. electronics industry grew continued develop, Ohmite continued evolving service ever changing design requirements. 1953, company moved into newly built factory offices Skokie, Illinois. Through acquisition, Ohmite added wirewound capabilities Memcor-Truohm 1996 Ward Leonard Resistors 1999. With this acquisition, Ohmite added production facility Barbados W.I. enabling company expand into tighter tolerance technology. Victoreen Components, experienced specialist Thick Film technology high voltage applications, added Ohmite family 1999. 1998, Ohmite acquired Heico Companies LLC; multinational, U.S. based holding company. Skokie plant after many years service vacated operations were moved Matamoros, Mexico while Headquarters remained Rolling Meadows, Illinois. 2006 Ohmite continue grow enhance product offerings acquiring Vishay's Angstrohm Rheostat Ultronix Precision Resistor divisions. Strengthened backing Heico Companies LLC, Ohmite strives maintain flexibility needed handle both large small requirements. Made order parts always considered technologies always being evaluated.

Current sense resistors enable measurement current flow circuit monitoring voltage drop across precisely calibrated resistance. chip features four terminals, also known "Kelvin" configuration. This configuration enables current applied through opposite terminals sensing voltage measured across other terminals, eliminating resistance temperature coefficient terminals more accurate current measurement. Isolating voltage current terminals (see schematic) facilitates very accurate current measurement. Ohmite's proprietary technology offers excellent Temperature Coefficient Resistance (TCR) even very resistance values. resistive element consists durable, anti-corrosive metal alloy that combines reliable performance with ability withstand harsh environments.

They manufactured unique process that molds vitreous enamel over resistive element, helping ensure consistent dimensions. This uniformity permits Series resistors mounted clips, creating heat-sinking benefit (see next page). durable vitreous enamel coating, which totally lead free, permits Series resistors maintain hard coating while operating high temperatures. Mechanical integrity enhanced all-welded construction.
