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-1videotape 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-Janalog TV system. It is often referred to simply as EIAJ, or sometimes as FM-FM audio.
The Japanese technical standard JIS-C-7102 provides a method of developing part numbers for transistor devices.[1] The part number has up to five fields, for example in the number 2SC82DA:
The first digit "2" indicates this is a 3 lead device ( a diode would have a prefix numeral 1)
The letters "S" is common for all EIAJ registered semiconductors
The following letter designates polarity and general application of the device. For transistors:
The numerals following indicate the order in which the application was received, starting at 11
A suffix letter indicates improved characteristics
Historyedit
in 1948, Electronic Industries Association of Japan has first appeared in Taito, Tokyo, Japan. In 2000, Electronic Industries Association of Japan became a Pending merger with JEIDA and was Reorganized into JEITA.
