TO-99
In electronics, TO-5 (Transistor Outline 5) is a designation for a standardized metal semiconductor package used for transistors and some integrated circuits. The ''TO'' element stands for "transistor outline" and refers to a series of technical drawings produced by JEDEC. The first commercial silicon transistors, the 2N696 and 2N697 from Fairchild Semiconductor, came in a TO-5 package. Construction and orientation The tab is located 45° from pin 1, which is typically the emitter. The typical TO-5 package has a base diameter of , a cap diameter of , a cap height of . The pins are isolated from the package by individual glass-metal seals, or by a single resin potting. Sometimes one pin is connected directly to the metal case. Variants Several variants of the original TO-5 package have the same cap dimensions but differ in the number and length of the leads (wires). Somewhat incorrectly, TO-5 and TO-39 are often used in manufacturer's literature as synonyms for any package with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rosstandart
Federal Agency for Technical Regulation and Metrology (Rosstandart) () is the Russian federal government agency that serves as a national standardization body of the Russian Federation. It was previously known as Gosstandart. It is subordinated to the Ministry of Industry and Trade. History On September 15, 1925, by a resolution of the Council of People's Commissars of the USSR, an all-Union body in the field of standardization was created, the Committee for Standardization under the Council of Labor and Defense (Gosstandart). The introduction of state management of standardization in the country served as the beginning of systematic work in all sectors of the economy. On May 7, 1926, the first all-Union standard was approved - OST 1 “Wheat. Breeding grades of grain. Nomenclature". In 1946, the International Organization for Standardization (ISO) was established. The USSR took over the work of the secretariats of technical committees: 37 “Terminology (general principles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GOST
GOST () refers to a set of international technical standards maintained by the Euro-Asian Council for Standardization, Metrology and Certification (EASC), a regional standards organization operating under the auspices of the Commonwealth of Independent States (CIS). All sorts of regulated standards are included, with examples ranging from charting rules for design documentation to recipes and nutritional facts of Soviet-era brand names. The latter have become generic, but may only be sold under the label if the technical standard is followed, or renamed if they are reformulated. History GOST standards were originally developed by the government of the Soviet Union as part of its national standardization strategy. The word GOST ( Russian: ) is an acronym for ''gosudarstvennyy standart'' (Russian: '), which means ''government standard''. The history of national standards in the USSR can be traced back to 1925, when a government agency, later named Gosstandart, was establi ...

Gosstandart
Gosstandart () was the Soviet government agency responsible for standardization, metrology, and quality management. The name is an abbreviation for ''Gosudarstvennyy standart'' (‘State Standard’). History Established in 1925, as a committee for standardization within the USSR Council of Labor and Defence, ''Gosstandart'' was at first put in charge of inspecting measuring instruments used in industrial and agricultural production and later was tasked with developing, updating, and disseminating GOST standards. Over the course of its existence, the agency was reformed a number of times, receiving a new name with each transformation: the ''National Committee for Standardization''; the ''Committee for Standards, Metrology, and Measuring Instruments''; the ''State Committee for Standards''; the ''State Committee for Standards and Product Quality Management''. The agency received its nickname, ''Gosstandart'', in 1970. Later years After the dissolution of the USSR, the Russian go ...

British Standards
British Standards (BS) are the standards produced by the BSI Group which is incorporated under a royal charter and which is formally designated as the national standards body (NSB) for the UK. The BSI Group produces British Standards under the authority of the charter, which lays down as one of the BSI's objectives to: Formally, as stated in a 2002 memorandum of understanding between the BSI and the United Kingdom Government, British Standards are defined as: Products and services which BSI certifies as having met the requirements of specific standards within designated schemes are awarded the Kitemark. History BSI Group began in 1901 as the ''Engineering Standards Committee'', led by James Mansergh, to standardize the number and type of steel sections, in order to make British manufacturers more efficient and competitive. Over time the standards developed to cover many aspects of tangible engineering, and then engineering methodologies including quality systems, saf ...

EIAJ
Founded in 1948, the Electronic Industries Association of Japan (EIAJ) was one of two Japanese electronics trade organizations that were merged into the Japan Electronics and Information Technology Industries Association (JEITA). Prior to the merger, EIAJ created a number of electronics industry standards that have had some use outside Japan, including: *The EIAJ connectors used for DC power (EIAJ RC-5320A, EIAJ RC-5321, and EIAJ RC-5322 *The D-Terminal connector (RC-5237), used instead of three RCA plugs for component video connections. *The TOSLINK (EIAJ Optical, RC-5720C) optical S/PDIF audio connector. *The EIAJ-1 videotape format, the first standardized format for industrial/non-broadcast video tape recording, released in 1969. Another standard is the multi-channel TV sound system used with the NTSC-J analog TV system. It is often referred to simply as EIAJ, or sometimes as FM-FM audio.
