I came by a few electronic components that I don't recognize them from their shape nor their letters printed on the PCB. Is there a full list of the names and abbreviation of electronic components?

Some of the letters that I don't know their components' names.

enter image description here

  • Q (SMD with 2 terminals from one side and 1 terminal from the opposite side)

  • Q (Not SMD with 3 terminals & has a tower shape, 3/4 circle)

  • IC (3 terminals from one side and 1 wide terminal from the opposite side)

  • OJ (It's like SMD resistance with a 0 written on top of it)

  • X (It might belong to the below component with SC8.000 writing on top of it)

  • SC8.000 written on the curved metal rectangular in the picture below.

  • \$\begingroup\$ Are you asking for a full list (can't and doesn't exist) or for information on these specific things (much easier)? \$\endgroup\$ – Marcus Müller May 2 at 19:23
  • \$\begingroup\$ The PWB has reference designators that should match the schematic. There is no universal list, although this list is fairly close to what I have used in my career. en.wikipedia.org/wiki/Reference_designator \$\endgroup\$ – Mattman944 May 2 at 19:51

That would require a) full knowledge of all possible components and b) full cooperation of all engineers ever. So, no, such a list does not exist.

There's a few standards, but your board markings agree with none that I would be aware of. So, we can only help you "acutely" map the letters for this very board, not for other boards to types of devices:

  • Q is typically associated with transistors. There's multiple legend about where that hails from. It's probably a thing from vacuum tube times.
  • IC is just "integrated circuit". That can refer to anything from a single transistor with a biasing resistor in the same package, to a billion-gates CPU. In your 4-pin case, probably either such a self-biased transistor, a diode pair, or a linear voltage regulator, but it might also be a switch-mode supply, a or some other power electronics.
  • OJ is "orange juice". The "O" is probably a zero, and it's probably supposed to mean "0 Ω resistor or jumper", which "explains" the J
  • X is for Crystal
  • And that's exactly what the silver component is, a crystal oscillator. "SC" stands for "stress cut", and describes in which direction the piezoelectric crystal inside the metal dome has been sliced. 8 probably means "8 MHz", that's a common resonant frequency.

  • \$\begingroup\$ Hmm. Still works okay for me. It's on Aliexpress. Is that blocked for you? I'll see if I can pick up an image. \$\endgroup\$ – jonk May 2 at 19:33

    \$\begingroup\$ @AshrafAlshahawy you can't test anything on a board. And the markings on the component will tell you more than you could test with a DMM (which really tells you very little about a semiconductor, anyway) \$\endgroup\$ – Marcus Müller May 5 at 21:16
