Especially valuable is the method of referencing and annotating cables plus their connectors within and outside assemblies. Any number of sub-assemblies may be defined until finally reaching the component.
The reference designator usually consists of one or two letters followed by a number, e. Students Click Here Join Us!
A reference designator unambiguously identifies a component in an electrical schematic or on a printed circuit board. Register now while it’s still free! The Eng-Tips staff will check 200-1975 out and take appropriate action.
This standard, along with 200-19755provide the electrical designer with guidance on how to properly reference and annotate everything from a single circuit board to a collection of complete enclosures. Cathode ray tube CR: Liquid crystal display LDR: The number is sometimes followed by a letter, indicating that components are grouped or matched with each other, e.

For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays. IEEE or “Standard Reference Designations for Electrical and Electronics Parts and Equipments” is a standard that was used to define referencing naming systems ieer collections of electronic equipment.

IEEE was ratified in Note that IEEE  defines separate class designation letters for separable assemblies class designation ‘A’ and inseparable assemblies class designation ‘U’.
