KEMET Capacitor Company, USA

The development of KEMET's automatic machinery requires the rapid expansion of a large number of high-quality dry pipes to be matched with the use of vacuum tubes. In fact, it is estimated that over 80% of the vacuum tubes used by the Allied forces during World War II were operated by KEMET company. The business continued to grow and prosper until early 1950, when Bell Telephone Laboratories invented the transistor. Due to the stagnation of the getter business where transistors began to replace electronic vacuum tubes. Fortunately, KEMET and Bell Laboratories also invented solid tantalum capacitors, which are used in conjunction with low-voltage transistor circuits (semiconductors). Due to the experience of American Union Carbide in high-temperature metals and alloys, it has been selected as the "new product" of KEMET solid tantalum capacitor company to supplement the getter product line and provide vehicles for future development.
