Sprague Electric Company was an electronic component maker founded by Robert C. Sprague in 1926. Sprague was best known for making a large line of capacitors used in a wide variety of electrical and electronic in commercial, industrial and military/space applications.
Founder of Sprague Electric, manufacturer of capacitors Robert C. Sprague (August 2, 1900 – September 27, 1991) was the son of Frank J. Sprague and Harriet Sprague. Sprague founded Sprague Electric (originally Sprague Specialties Company), Quincy, Massachusetts in 1926, and served as president from 1926-1953 and chief executive from 1953-1971.
Vishay Intertechnology, Inc. is an American manufacturer of discrete semiconductors and passive electronic components founded by Polish-born businessman Felix Zandman.Vishay has manufacturing plants in Israel, Asia, Europe, and the Americas where it produces rectifiers, diodes, MOSFETs, optoelectronics, selected integrated circuits, resistors, capacitors, and inductors.
A capacitor is a passive device on a circuit board that stores electrical energy in an electric field by virtue of accumulating electric charges on two close surfaces insulated from each other. This is a list of known capacitor manufacturers, their headquarters country of origin, and year founded. The oldest capacitor companies were founded ...
PECs contained only resistors and capacitors arranged in circuits to simplify construction of tube equipment. Also, their voltage ratings were suitable for tubes. Later, hybrid ICs contained transistors, and often monolithic integrated circuits. Their voltage ratings were suitable for the transistors they contained.
The strip acted as a series of resistors; the lumped capacitors were formed by fusion whereas inverse-biased p-n junctions acted as distributed capacitors. [21] Johnson did not offer a technological procedure, and it is not known whether he produced an actual device. In 1959, a variant of his proposal was implemented and patented by Jack Kilby ...
