Small 56.9 KB PDF for the 2SD1679, with an extra E suffix in the name that is not explained further.

The 34.0 KB PDF named 2SK3557 is indexed as a schematic, but its name is a JIS component number, so it is almost certainly a datasheet.

For the 2SK2744 this 177 KB PDF provides component-level reference material, although the index lists it among schematics.

Short PDF of 23.2 KB named for the 2SK2324 part. In JIS nomenclature 2SK denotes an N-channel FET, so this schematic-labelled file is presumably a brief datasheet.

Brief 40.6 KB PDF for the 2SC4543, carrying an _E suffix whose meaning the name does not explain, and filed under schematics.

Reference document for the 2SC1815, a 310 KB PDF classed as a schematic. In JIS numbering the 2SC prefix denotes an NPN bipolar transistor, and the file is most likely…

Indexed as a schematic, this 40.2 KB PDF is named 2SB1220 with an _E suffix and almost certainly contains the datasheet for that JIS transistor.

Specifications for the 2SA1873 PNP transistor, provided as a 247 KB PDF. The 2SA prefix comes from the JIS semiconductor naming system and denotes a PNP bipolar part, so…

Part number 1N6392 names this 43.5 KB PDF, a component datasheet for a JEDEC 1N-series device filed in the schematic category.

This 132 KB PDF is labelled 50SQ060 and indexed as a schematic, without any laptop model or board number.

Schematic in PDF for the Lenovo ThinkPad A285 laptop, board NM-B751. The NM- prefix marks an LCFC design, Lenovo's own ODM, and these diagrams usually include a block…

Spanish course section 3.1 on the multimeter, provided as a 526 KB PDF within the workshop equipment chapter. No meter model is mentioned.

NEC schematic in PDF for a design labelled AF1, an internal project or model code. The name states no board number or revision, so look at the title block inside and…

Compal NM-A281P schematic, revision R0.4, compressed into an 839 KB RAR file. The laptop model and brand are not named, and NM-series numbers are associated with Compal…

Quanta U92 circuit diagram, revision R1A dated 2013-03-27, supplied as a 987 KB PDF and apparently a duplicate of another file with the same title.

Lenovo schematic labelled only with the code 80A, which gives little to identify the exact model, board number or revision.

Lenovo E40 circuit diagram as a 1.38 MB PDF, whose name states the model alone. Board number, designer and revision should be read from the pages, and a similarly sized…

PDF schematic set for the Gigabyte GA-Z97X-UD5H, labelled revision R111 and stored in a RAR archive.

PDF schematic for the Samsung SM-G355H, 3.21 MB, with an extra HrM suffix in the name whose meaning is not certain and may denote a particular variant or document…

Schematic for the MSI Wind netbook family, naming the U100, U92 and U90 models on board MS-N011.

Raspberry Pi Model B+ schematics, version 1.2, an 81.2 KB PDF. The pages document the power input and protection, switching regulators, USB and Ethernet section, HDMI…

PDF for the 2SC1172, 74.4 KB, listed among schematics with no further detail in its name.

PDF for the BU4508DX, a small 48.8 KB document filed as a schematic but most likely the part datasheet.

A 365 KB PDF for the 2SK2859, filed under the schematic type though it is most probably a manufacturer datasheet. Nothing other than the part number appears in the name.

The 2SK1839 is covered in this 84.9 KB PDF, filed under schematics though the name points to a single semiconductor part.

Filed as a schematic, this 464 KB PDF carries just the name 2SC4322 and should be read as a transistor datasheet.

Datasheet PDF for the 2SC3931, 60.7 KB, with the _E suffix common to this group of files and listed as a schematic.
