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.

Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework. The unit is the highest level of demarcation in a system and is always a numeral. 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.

From Wikipedia, the free encyclopedia. IEEE or “Standard Iee Designations for Electrical and Electronics Parts and Equipments” is a standard that was used to define referencing naming systems for collections of electronic equipment.

Especially valuable is the method of referencing and annotating cables plus their connectors within and outside assemblies. Printed circuit board PLC: It’s easy to join and it’s free. IEEE was ratified in Close this window and log in.

Circulator or directional coupler. Cathode ray tube CR: Digital signal processor FET: Download Now White Paper: Junction gate field-effect transistor LA: Vacuum fluorescent display VT: Subsequent demarcation are called assemblies and always have the Class Letter “A” as a prefix following by a sequential number starting with 1.
