Some manufacturers specify a three-character date code with a two-digit week number following the year letter. [ 34 ] IEC 60062 also specifies a four-character year/week code.
The current international standard defining marking codes for resistors and capacitors is IEC 60062:2016. [5] In addition to the color code, these standards define a letter and digit code named RKM code for resistors and capacitors. Color bands were used because they were easily and cheaply printed on tiny components.
Examples of the IEC nomenclature are batteries coded R20, 4R25X, 4LR25-2, 6F22, 6P222/162, CR17345 and LR2616J. The letters and numbers in the code indicate the number of cells, cell chemistry, shape, dimensions, the number of parallel paths in the assembled battery and any modifying letters deemed necessary.
The leading digit is the major industry identifier (MII), followed by 5 digits, which together make up the IIN. This IIN is paired with an individual account identification number, and a single digit checksum. [1] In 2015, ISO TC68/SC9 began work on implementing a change to ISO/IEC 7812 to increase the length of the IIN to 8 digits.
It is developed by the IEC Technical Committee 1 (Terminology), and published as both the IEC 60050 series of standards and online as the Electropedia. The Electropedia database contains English and French definitions for more than 22 000 concepts, and provides terms in up to 18 other languages.
