KEMET Corporation is a manufacturer of tantalum, ceramic, film, aluminum electrolytic, paper and aluminum polymer capacitors. It is based in Simpsonville, South Carolina. KEMET Corporation began as Kemet Laboratories, established by Union Carbide Corporation after its purchase of the Cooper Research Company of Cleveland, Ohio, which had invented a promising high-temperature alloy. The name "KEMET" is a blend of the words "chemical" and "metallurgy." KEMET's first product used this high-temperature alloy for grid wires in vacuum tubes. In 1930, the product line was expanded to include barium-aluminum alloy getters, an essential element in vacuum tubes. KEMET's development of automatic machinery allowed production of getters in large quantities needed to match the rapid expansion of vacuum tube usage. It has been estimated that over 80% of the vacuum tubes used by the Allies during World War II contained KEMET getters. In the early 1950s when Bell Telephone Laboratories invented the transistor. As the transistor began to displace vacuum tubes in electronics, the getter business stagnated. Bell Laboratories had also invented the solid tantalum capacitor, which complemented the use of [ - ]
