The unit is the highest level of demarcation in a system and is always a numeral.
Vacuum fluorescent display VT: Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. Download Now Defense manufacturing is all about project manufacturing and project accounting. Digital signal processor FET: The IEEE renewed the standard in the s, but withdrew it from active support shortly thereafter. Socket connector for another item not P or J, paired with the letter symbol for that item XV for vacuum tube socket, XF for fuse holder, XA for printed circuit assembly connector, XU for integrated circuit connector, XDS for light socket, etc.
Inductor or coil or iieee bead. This page was last edited on 25 Octoberat The reference designator usually consists of one or two letters followed by a number, e. Retrieved from ” https: From Wikipedia, the free encyclopedia. IEEE or “Standard Reference Designations for Electrical and Electronics Parts and Equipments” is a standard that was used to define referencing naming systems for collections of electronic equipment.
Note that IEEE  defines separate class designation letters for separable assemblies class designation ‘A’ and inseparable assemblies class designation ‘U’.

It breaks down a system into units, and then any number of sub-assemblies. The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e. Cathode ray tube CR: Views Read Edit View history.
Separable assembly or sub-assembly e. Metal-oxide-semiconductor field-effect transistor MOV: Miniature circuit breaker MIC: IEEE was ratified in Thin-film transistor display TH: Did any document take its place as regards section 8 requiring marking of ref designations on equipment? Subsequent demarcation are called assemblies and always have the Class Letter “A” as a prefix following by a sequential number starting with 1.
Especially valuable is the method of referencing and annotating cables plus their connectors within and outside assemblies. Metal oxide varistor NE: Join your peers on the Internet’s largest technical engineering professional community.
