    en.wikipedia.org/wiki/Reference_designator

    A reference designator unambiguously identifies the location of a component within an electrical schematic or on a printed circuit board.The reference designator usually consists of one or two letters followed by a number, e.g. C3, D1, R4, U15.

  3. Engineering drawing abbreviations and symbols - Wikipedia

    en.wikipedia.org/wiki/Engineering_drawing...

    The issuance of a drawing from the engineering/design activity to the production activity. In other words, the event when a draft becomes a completed, official document. A stamp on the drawing saying "ISSUED" documents that RTP has occurred. RTV: room-temperature vulcanizing; return to vendor: 1. RTV sealants, a way to seal joints. 2.

  4. Electronic symbol - Wikipedia

    en.wikipedia.org/wiki/Electronic_symbol

    Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...

    en.wikipedia.org/wiki/Functional_block_diagram

    The block diagram can use additional schematic symbols to show particular properties. Since the late 1950s, functional block diagrams have been used in a wide range applications, from systems engineering to software engineering. They became a necessity in complex systems design to "understand thoroughly from exterior design the operation of the ...
