Gas discharge tube IC: IEEE Reaffirmed Did any document take its place as regards section 8 requiring marking of ref designations on equipment? Printed circuit board PLC: Zero sequence current transformer, also called a window-type current transformer. Resources Digital Transformation may be defined in a number of different ways by analysts or enterprise software vendors.

Defense manufacturing is all about project manufacturing and project accounting. Junction gate field-effect transistor LA: 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.
From Wikipedia, the free encyclopedia. Liquid crystal display LDR: This standard, along with IEEEprovide the electrical designer with guidance on how to properly reference and annotate everything from a single circuit board to a collection of complete enclosures.
Note that IEEE  defines separate class designation letters for separable assemblies class designation ‘A’ and inseparable assemblies class designation ‘U’. For example, the letter R is a reference prefix for the resistors of an assembly, C for capacitors, K for relays.
A reference designator unambiguously identifies a component in an electrical schematic or on a printed circuit board.
